This PR separates the status of a `StreamingQuery` into two separate APIs: - `status` - describes the status of a `StreamingQuery` at this moment, including what phase of processing is currently happening and if data is available. - `recentProgress` - an array of statistics about the most recent microbatches that have executed. A recent progress contains the following information: ``` { "id" : "2be8670a-fce1-4859-a530-748f29553bb6", "name" : "query-29", "timestamp" : 1479705392724, "inputRowsPerSecond" : 230.76923076923077, "processedRowsPerSecond" : 10.869565217391303, "durationMs" : { "triggerExecution" : 276, "queryPlanning" : 3, "getBatch" : 5, "getOffset" : 3, "addBatch" : 234, "walCommit" : 30 }, "currentWatermark" : 0, "stateOperators" : [ ], "sources" : [ { "description" : "KafkaSource[Subscribe[topic-14]]", "startOffset" : { "topic-14" : { "2" : 0, "4" : 1, "1" : 0, "3" : 0, "0" : 0 } }, "endOffset" : { "topic-14" : { "2" : 1, "4" : 2, "1" : 0, "3" : 0, "0" : 1 } }, "numRecords" : 3, "inputRowsPerSecond" : 230.76923076923077, "processedRowsPerSecond" : 10.869565217391303 } ] } ``` Additionally, in order to make it possible to correlate progress updates across restarts, we change the `id` field from an integer that is unique with in the JVM to a `UUID` that is globally unique.

_This is the master branch version of #15986; the original description follows:_ This patch fixes a critical resource leak in the TaskScheduler which could cause RDDs and ShuffleDependencies to be kept alive indefinitely if an executor with running tasks is permanently lost and the associated stage fails. This problem was originally identified by analyzing the heap dump of a driver belonging to a cluster that had run out of shuffle space. This dump contained several `ShuffleDependency` instances that were retained by `TaskSetManager`s inside the scheduler but were not otherwise referenced. Each of these `TaskSetManager`s was considered a "zombie" but had no running tasks and therefore should have been cleaned up. However, these zombie task sets were still referenced by the `TaskSchedulerImpl.taskIdToTaskSetManager` map. Entries are added to the `taskIdToTaskSetManager` map when tasks are launched and are removed inside of `TaskScheduler.statusUpdate()`, which is invoked by the scheduler backend while processing `StatusUpdate` messages from executors. The problem with this design is that a completely dead executor will never send a `StatusUpdate`. There is [some code](https://github.com/apache/spark/blob/072f4c518cdc57d705beec6bcc3113d9a6740819/core/src/main/scala/org/apache/spark/scheduler/TaskSchedulerImpl.scala#L338) in `statusUpdate` which handles tasks that exit with the `TaskState.LOST` state (which is supposed to correspond to a task failure triggered by total executor loss), but this state only seems to be used in Mesos fine-grained mode. There doesn't seem to be any code which performs per-task state cleanup for tasks that were running on an executor that completely disappears without sending any sort of final death message. The `executorLost` and [`removeExecutor`](https://github.com/apache/spark/blob/072f4c518cdc57d705beec6bcc3113d9a6740819/core/src/main/scala/org/apache/spark/scheduler/TaskSchedulerImpl.scala#L527) methods don't appear to perform any cleanup of the `taskId -> *` mappings, causing the leaks observed here. This patch's fix is to maintain a `executorId -> running task id` mapping so that these `taskId -> *` maps can be properly cleaned up following an executor loss. There are some potential corner-case interactions that I'm concerned about here, especially some details in [the comment](https://github.com/apache/spark/blob/072f4c518cdc57d705beec6bcc3113d9a6740819/core/src/main/scala/org/apache/spark/scheduler/TaskSchedulerImpl.scala#L523 ) in `removeExecutor`, so I'd appreciate a very careful review of these changes. I added a new unit test to `TaskSchedulerImplSuite`. /cc kayousterhout and markhamstra, who reviewed #15986.

## What changes were proposed in this pull request? ExistenceJoin should be treated the same as LeftOuter and LeftAnti, not InnerLike and LeftSemi. This is not currently exposed because the rewrite of [NOT] EXISTS OR ... to ExistenceJoin happens in rule RewritePredicateSubquery, which is in a separate rule set and placed after the rule PushPredicateThroughJoin. During the transformation in the rule PushPredicateThroughJoin, an ExistenceJoin never exists. The semantics of ExistenceJoin says we need to preserve all the rows from the left table through the join operation as if it is a regular LeftOuter join. The ExistenceJoin augments the LeftOuter operation with a new column called exists, set to true when the join condition in the ON clause is true and false otherwise. The filter of any rows will happen in the Filter operation above the ExistenceJoin. Example: A(c1, c2): { (1, 1), (1, 2) } // B can be any value as it is irrelevant in this example B(c1): { (NULL) } select A.* from A where exists (select 1 from B where A.c1 = A.c2) or A.c2=2 In this example, the correct result is all the rows from A. If the pattern ExistenceJoin around line 935 in Optimizer.scala is indeed active, the code will push down the predicate A.c1 = A.c2 to be a Filter on relation A, which will incorrectly filter the row (1,2) from A. ## How was this patch tested? Since this is not an exposed case, no new test cases is added. The scenario is discovered via a code review of another PR and confirmed to be valid with peer.

For example, the line below: ```scala /** Return an RDD with the pairs from `this` whose keys are not in `other`. */ ``` So, we could work around this as below: ```scala /** * Return an RDD with the pairs from `this` whose keys are not in `other`. */ ``` - javadoc - **Before**  - **After**  - scaladoc (this one looks fine either way) - **Before**  - **After**  I suspect this is related with SPARK-16153 and genjavadoc issue in ` typesafehub/genjavadoc#85`. ## How was this patch tested?

## What changes were proposed in this pull request? A TorrentBroadcast is serialized and compressed first, then splitted as fixed size blocks, if any block is corrupt when fetching from remote, the decompression/deserialization will fail without knowing which block is corrupt. Also, the corrupt block is kept in block manager and reported to driver, so other tasks (in same executor or from different executor) will also fail because of it. This PR add checksum for each block, and check it after fetching a block from remote executor, because it's very likely that the corruption happen in network. When the corruption happen, it will throw the block away and throw an exception to fail the task, which will be retried. Added a config for it: `spark.broadcast.checksum`, which is true by default. ## How was this patch tested? Existing tests.

[SPARK-18339][SPARK-18513][SQL] Don't push down current_timestamp for filters in StructuredStreaming and persist batch and watermark timestamps to offset log. ## What changes were proposed in this pull request? For the following workflow: 1. I have a column called time which is at minute level precision in a Streaming DataFrame 2. I want to perform groupBy time, count 3. Then I want my MemorySink to only have the last 30 minutes of counts and I perform this by .where('time >= current_timestamp().cast("long") - 30 * 60) what happens is that the `filter` gets pushed down before the aggregation, and the filter happens on the source data for the aggregation instead of the result of the aggregation (where I actually want to filter). I guess the main issue here is that `current_timestamp` is non-deterministic in the streaming context and shouldn't be pushed down the filter. Does this require us to store the `current_timestamp` for each trigger of the streaming job, that is something to discuss. Furthermore, we want to persist current batch timestamp and watermark timestamp to the offset log so that these values are consistent across multiple executions of the same batch. brkyvz zsxwing tdas ## How was this patch tested? A test was added to StreamingAggregationSuite ensuring the above use case is handled. The test injects a stream of time values (in seconds) to a query that runs in complete mode and only outputs the (count) aggregation results for the past 10 seconds.

This change modifies the method used to propagate encryption keys used during shuffle. Instead of relying on YARN's UserGroupInformation credential propagation, this change explicitly distributes the key using the messages exchanged between driver and executor during registration. When RPC encryption is enabled, this means key propagation is also secure. This allows shuffle encryption to work in non-YARN mode, which means that it's easier to write unit tests for areas of the code that are affected by the feature. The key is stored in the SecurityManager; because there are many instances of that class used in the code, the key is only guaranteed to exist in the instance managed by the SparkEnv. This path was chosen to avoid storing the key in the SparkConf, which would risk having the key being written to disk as part of the configuration (as, for example, is done when starting YARN applications). Tested by new and existing unit tests (which were moved from the YARN module to core), and by running apps with shuffle encryption enabled.

## What changes were proposed in this pull request? We currently push down join conditions of a Left Anti join to both sides of the join. This is similar to Inner, Left Semi and Existence (a specialized left semi) join. The problem is that this changes the semantics of the join; a left anti join filters out rows that matches the join condition. This PR fixes this by only pushing down conditions to the left hand side of the join. This is similar to the behavior of left outer join. ## How was this patch tested?

## What changes were proposed in this pull request? This PR avoids a compilation error due to more than 64KB Java byte code size. This error occur since generated java code `SpecificSafeProjection.apply()` for nested JavaBeans is too big. This PR avoids this compilation error by splitting a big code chunk into multiple methods by calling `CodegenContext.splitExpression` at `InitializeJavaBean.doGenCode` An object reference for JavaBean is stored to an instance variable `javaBean...`. Then, the instance variable will be referenced in the split methods.

## What changes were proposed in this pull request? The `CollapseWindow` optimizer rule changes the order of output attributes. This modifies the output of the plan, which the optimizer cannot do. This also breaks things like `collect()` for which we use a `RowEncoder` that assumes that the output attributes of the executed plan are equal to those outputted by the logical plan. ## How was this patch tested? I have updated an incorrect test in `CollapseWindowSuite`. Author: Herman van Hovell <hvanhovell@databricks.com> Closes #16027 from hvanhovell/SPARK-18604.

## What changes were proposed in this pull request? Janino can optimize `true ? a : b` into `a` or `false ? a : b` into `b`, or if/else with literal condition, so we should use literal as `ev.isNull` if possible. ## How was this patch tested?

## What changes were proposed in this pull request? In Spark 2.1, we did a lot of refactor for `HiveExternalCatalog` and related code path. These refactor may introduce external behavior changes and break backward compatibility. e.g. http://issues.apache.org/jira/browse/SPARK-18464 To avoid future compatibility problems of `HiveExternalCatalog`, this PR dumps some typical table metadata from tables created by 2.0, and test if they can recognized by current version of Spark. ## How was this patch tested? test only change Author: Wenchen Fan <wenchen@databricks.com> Closes #16003 from cloud-fan/test.

### What changes were proposed in this pull request? Currently, the name validation checks are limited to table creation. It is enfored by Analyzer rule: `PreWriteCheck`. However, table renaming and database creation have the same issues. It makes more sense to do the checks in `SessionCatalog`. This PR is to add it into `SessionCatalog`. ### How was this patch tested? Added test cases Author: gatorsmile <gatorsmile@gmail.com> Closes #16018 from gatorsmile/nameValidate.

## What changes were proposed in this pull request? Currently, `OuterReference` is not `NamedExpression`. So, it raises 'ClassCastException` when it used in projection lists of IN correlated subqueries. This PR aims to support that by making `OuterReference` as `NamedExpression` to show correct error messages. ```scala scala> sql("CREATE TEMPORARY VIEW t1 AS SELECT * FROM VALUES 1, 2 AS t1(a)") scala> sql("CREATE TEMPORARY VIEW t2 AS SELECT * FROM VALUES 1 AS t2(b)") scala> sql("SELECT a FROM t1 WHERE a IN (SELECT a FROM t2)").show java.lang.ClassCastException: org.apache.spark.sql.catalyst.expressions.OuterReference cannot be cast to org.apache.spark.sql.catalyst.expressions.NamedExpression ``` ## How was this patch tested?

## What changes were proposed in this pull request? The expression `in(empty seq)` is invalid in some data source. Since `in(empty seq)` is always false, we should generate `in(empty seq)` to false literal in optimizer. The sql `SELECT * FROM t WHERE a IN ()` throws a `ParseException` which is consistent with Hive, don't need to change that behavior. ## How was this patch tested? Add new test case in `OptimizeInSuite`. Author: jiangxingbo <jiangxb1987@gmail.com> Closes #15977 from jiangxb1987/isin-empty. (cherry picked from commit e2fb9fd3) Signed-off-by:

## What changes were proposed in this pull request? In `HyperLogLogPlusPlus`, if the relative error is so small that p >= 19, it will cause ArrayIndexOutOfBoundsException in `THRESHOLDS(p-4)` . We should check `p` and when p >= 19, regress to the original HLL result and use the small range correction they use. The pr also fixes the upper bound in the log info in `require()`. The upper bound is computed by: ``` val relativeSD = 1.106d / Math.pow(Math.E, p * Math.log(2.0d) / 2.0d) ``` which is derived from the equation for computing `p`: ``` val p = 2.0d * Math.log(1.106d / relativeSD) / Math.log(2.0d) ``` ## How was this patch tested? add test cases for: 1. checking validity of parameter relatvieSD 2. estimation with smaller relative error so that p >= 19 Author: Zhenhua Wang <wzh_zju@163.com> Author: wangzhenhua <wangzhenhua@huawei.com> Closes #15990 from wzhfy/hllppRsd.

[SPARK-3359][BUILD][DOCS] More changes to resolve javadoc 8 errors that will help unidoc/genjavadoc compatibility ## What changes were proposed in this pull request? This PR only tries to fix things that looks pretty straightforward and were fixed in other previous PRs before. This PR roughly fixes several things as below: - Fix unrecognisable class and method links in javadoc by changing it from `[[..]]` to `` `...` `` ``` [error] .../spark/sql/core/target/java/org/apache/spark/sql/streaming/DataStreamReader.java:226: error: reference not found [error] * Loads text files and returns a {link DataFrame} whose schema starts with a string column named ``` - Fix an exception annotation and remove code backticks in `throws` annotation Currently, sbt unidoc with Java 8 complains as below: ``` [error] .../java/org/apache/spark/sql/streaming/StreamingQuery.java:72: error: unexpected text [error] * throws StreamingQueryException, if <code>this</code> query has terminated with an exception. ``` `throws` should specify the correct class name from `StreamingQueryException,` to `StreamingQueryException` without backticks. (see [JDK-8007644](https://bugs.openjdk.java.net/browse/JDK-8007644)). - Fix `[[http..]]` to `<a href="http..."></a>`. ```diff - * [[https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https Oracle - * blog page]]. + * <a href="https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https "> + * Oracle blog page</a>. ``` `[[http...]]` link markdown in scaladoc is unrecognisable in javadoc. - It seems class can't have `return` annotation. So, two cases of this were removed. ``` [error] .../java/org/apache/spark/mllib/regression/IsotonicRegression.java:27: error: invalid use of return [error] * return New instance of IsotonicRegression. ``` - Fix < to `<` and > to `>` according to HTML rules. - Fix `</p>` complaint - Exclude unrecognisable in javadoc, `constructor`, `todo` and `groupname`. ## How was this patch tested? Manually tested by `jekyll build` with Java 7 and 8 ``` java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode) ``` ``` java version "1.8.0_45" Java(TM) SE Runtime Environment (build 1.8.0_45-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode) ``` Note: this does not yet make sbt unidoc suceed with Java 8 yet but it reduces the number of errors with Java 8.
