In `DataFrame.describe()`, the `count` aggregate produces an integer, the `avg` and `stdev` aggregates produce doubles, and `min` and `max` aggregates can produce varying types depending on what type of column they're applied to.

This is similar to #5999, but for streaming. Roughly 200 lines are tests. One thing to note here is that we already do some kind of scoping thing for call sites, so this patch adds the new RDD operation scoping logic in the same place. Also, this patch adds a `try finally` block to set the relevant variables in a safer way. tdas zsxwing ------------------------ **Before** <img src="https://cloud.githubusercontent.com/assets/2133137/7625996/d88211b8-f9b4-11e4-90b9-e11baa52d6d7.png" width="450px"/> -------------------------- **After** <img src="https://cloud.githubusercontent.com/assets/2133137/7625997/e0878f8c-f9b4-11e4-8df3-7dd611b13c87.png" width="650px"/> Author: Andrew Or <andrew@databricks.com> Closes #6034 from andrewor14/dag-viz-streaming and squashes the following commits: 932a64a [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming e685df9 [Andrew Or] Rename createRDDWith 84d0656 [Andrew Or] Review feedback 697c086 [Andrew Or] Fix tests 53b9936 [Andrew Or] Set scopes for foreachRDD properly 1881802 [Andrew Or] Refactor DStream scope names again af4ba8d [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming fd07d22 [Andrew Or] Make MQTT lower case f6de871 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 0ca1801 [Andrew Or] Remove a few unnecessary withScopes on aliases fa4e5fb [Andrew Or] Pass in input stream name rather than defining it from within 1af0b0e [Andrew Or] Fix style 074c00b [Andrew Or] Review comments d25a324 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming e4a93ac [Andrew Or] Fix tests? 25416dc [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 9113183 [Andrew Or] Add tests for DStream scopes b3806ab [Andrew Or] Fix test bb80bbb [Andrew Or] Fix MIMA? 5c30360 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 5703939 [Andrew Or] Rename operations that create InputDStreams 7c4513d [Andrew Or] Group RDDs by DStream operations and batches bf0ab6e [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 05c2676 [Andrew Or] Wrap many more methods in withScope c121047 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 65ef3e9 [Andrew Or] Fix NPE a0d3263 [Andrew Or] Scope streaming operations instead of RDD operations

This PR introduces several performance optimizations to `HadoopFsRelation` and `ParquetRelation2`: 1. Moving `FileStatus` listing from `DataSourceStrategy` into a cache within `HadoopFsRelation`. This new cache generalizes and replaces the one used in `ParquetRelation2`. This also introduces an interface change: to reuse cached `FileStatus` objects, `HadoopFsRelation.buildScan` methods now receive `Array[FileStatus]` instead of `Array[String]`. 1. When Parquet task side metadata reading is enabled, skip reading row group information when reading Parquet footers. This is basically what PR #5334 does. Also, now we uses `ParquetFileReader.readAllFootersInParallel` to read footers in parallel. Another optimization in question is, instead of asking `HadoopFsRelation.buildScan` to return an `RDD[Row]` for a single selected partition and then union them all, we ask it to return an `RDD[Row]` for all selected partitions. This optimization is based on the fact that Hadoop configuration broadcasting used in `NewHadoopRDD` takes 34% time in the following microbenchmark. However, this complicates data source user code because user code must merge partition values manually. To check the cost of broadcasting in `NewHadoopRDD`, I also did microbenchmark after removing the `broadcast` call in `NewHadoopRDD`. All results are shown below. ### Microbenchmark #### Preparation code Generating a partitioned table with 50k partitions, 1k rows per partition: ```scala import sqlContext._ import sqlContext.implicits._ for (n <- 0 until 500) { val data = for { p <- (n * 10) until ((n + 1) * 10) i <- 0 until 1000 } yield (i, f"val_$i%04d", f"$p%04d") data. toDF("a", "b", "p"). write. partitionBy("p"). mode("append"). parquet(path) } ``` #### Benchmarking code ```scala import sqlContext._ import sqlContext.implicits._ import org.apache.spark.sql.types._ import com.google.common.base.Stopwatch val path = "hdfs://localhost:9000/user/lian/5k" def benchmark(n: Int)(f: => Unit) { val stopwatch = new Stopwatch() def run() = { stopwatch.reset() stopwatch.start() f stopwatch.stop() stopwatch.elapsedMillis() } val records = (0 until n).map(_ => run()) (0 until n).foreach(i => println(s"Round $i: ${records(i)} ms")) println(s"Average: ${records.sum / n.toDouble} ms") } benchmark(3) { read.parquet(path).explain(extended = true) } ``` #### Results Before: ``` Round 0: 72528 ms Round 1: 68938 ms Round 2: 65372 ms Average: 68946.0 ms ``` After: ``` Round 0: 59499 ms Round 1: 53645 ms Round 2: 53844 ms Round 3: 49093 ms Round 4: 50555 ms Average: 53327.2 ms ``` Also removing Hadoop configuration broadcasting: (Note that I was testing on a local laptop, thus network cost is pretty low.) ``` Round 0: 15806 ms Round 1: 14394 ms Round 2: 14699 ms Round 3: 15334 ms Round 4: 14123 ms Average: 14871.2 ms ``` Author: Cheng Lian <lian@databricks.com> Closes #6225 from liancheng/spark-7673 and squashes the following commits: 2d58a2b [Cheng Lian] Skips reading row group information when using task side metadata reading 7aa3748 [Cheng Lian] Optimizes FileStatusCache by introducing a map from parent directories to child files ba41250 [Cheng Lian] Reuses HadoopFsRelation FileStatusCache in ParquetRelation2 3d278f7 [Cheng Lian] Fixes a bug when reading a single Parquet data file b84612a [Cheng Lian] Fixes Scala style issue 6a08b02 [Cheng Lian] WIP: Moves file status cache into HadoopFSRelation -

Replace the DriverQuirks with JdbcDialect(s) (and MySQLDialect/PostgresDialect) and allow developers to change the dialects on the fly (for new JDBCRRDs only). Some types (like an unsigned 64bit number) can be trivially mapped to java. The status quo is that the RRD will fail to load. This patch makes it possible to overwrite the type mapping to read e.g. 64Bit numbers as strings and handle them afterwards in software. JDBCSuite has an example that maps all types to String, which should always work (at the cost of extra code afterwards). As a side effect it should now be possible to develop simple dialects out-of-tree and even with spark-shell.

This patch fixes two things: **SPARK-7627.** Cached RDDs no longer light up on the job page. This is a simple fix. **SPARK-7472.** Display skipped stages differently from normal stages. The latter is a major UX issue. Because we link the job viz to the stage viz even for skipped stages, the user may inadvertently click into the stage page of a skipped stage, which is empty. ------------------- <img src="https://cloud.githubusercontent.com/assets/2133137/7675241/de1a3da6-fcea-11e4-8101-88055cef78c5.png" width="300px" /> Author: Andrew Or <andrew@databricks.com> Closes #6171 from andrewor14/dag-viz-skipped and squashes the following commits: f261797 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-skipped 0eda358 [Andrew Or] Tweak skipped stage border color c604150 [Andrew Or] Tweak grayscale colors 7010676 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-skipped 762b541 [Andrew Or] Use special prefix for stage clusters to avoid collisions 51c95b9 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-skipped b928cd4 [Andrew Or] Fix potential leak + write tests for it 7c4c364 [Andrew Or] Show skipped stages differently 7cc34ce [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-skipped c121fa2 [Andrew Or] Fix cache color

[SPARK-7299][SQL] Set precision and scale for Decimal according to JDBC metadata instead of returned BigDecimal JIRA: https://issues.apache.org/jira/browse/SPARK-7299 When connecting with oracle db through jdbc, the precision and scale of `BigDecimal` object returned by `ResultSet.getBigDecimal` is not correctly matched to the table schema reported by `ResultSetMetaData.getPrecision` and `ResultSetMetaData.getScale`. So in case you insert a value like `19999` into a column with `NUMBER(12, 2)` type, you get through a `BigDecimal` object with scale as 0. But the dataframe schema has correct type as `DecimalType(12, 2)`. Thus, after you save the dataframe into parquet file and then retrieve it, you will get wrong result `199.99`. Because it is reported to be problematic on jdbc connection with oracle db. It might be difficult to add test case for it. But according to the user's test on JIRA, it solves this problem. Author: Liang-Chi Hsieh <viirya@gmail.com> Closes #5833 from viirya/jdbc_decimal_precision and squashes the following commits: 69bc2b5 [Liang-Chi Hsieh] Merge remote-tracking branch 'upstream/master' into jdbc_decimal_precision 928f864 [Liang-Chi Hsieh] Add comments. 5f9da94 [Liang-Chi Hsieh] Set up Decimal's precision and scale according to table schema instead of returned BigDecimal.

The `toString` method of `LogisticRegressionModel` calls `get` method on an Option (threshold) without a safeguard. In spark-shell, the following code `val model = algorithm.run(data).clearThreshold()` in lbfgs code will fail as `toString `method will be called right after `clearThreshold()` to show the results in the REPL. Author: Shuo Xiang <shuoxiangpub@gmail.com> Closes #6224 from coderxiang/getorelse and squashes the following commits: d5f53c9 [Shuo Xiang] use getOrElse for getting the threshold of LR model 5f109b4 [Shuo Xiang] Merge remote-tracking branch 'upstream/master' c5c5bfe [Shuo Xiang] Merge remote-tracking branch 'upstream/master' 98804c9 [Shuo Xiang] fix bug in topBykey and update test

Learnt a lesson from SPARK-7655: Spark should avoid to use `scala.concurrent.ExecutionContext.Implicits.global` because the user may submit blocking actions to `scala.concurrent.ExecutionContext.Implicits.global` and exhaust all threads in it. This could crash Spark. So Spark should always use its own thread pools for safety. This PR removes all usages of `scala.concurrent.ExecutionContext.Implicits.global` and uses proper thread pools to replace them. Author: zsxwing <zsxwing@gmail.com> Closes #6223 from zsxwing/SPARK-7693 and squashes the following commits: a33ff06 [zsxwing] Decrease the max thread number from 1024 to 128 cf4b3fc [zsxwing] Remove "import scala.concurrent.ExecutionContext.Implicits.global"
