In SparkContext method `setCheckpointDir`, a warning is issued when spark master is not local and the passed directory for the checkpoint dir appears to be local. In practice, when relying on HDFS configuration file and using a relative path for the checkpoint directory (using an incomplete URI without HDFS scheme, ...), this warning should not be issued and might be confusing. In fact, in this case, the checkpoint directory is successfully created, and the checkpointing mechanism works as expected. This PR uses the `FileSystem` instance created with the given directory, and checks whether it is local or not. (The rationale is that since this same `FileSystem` instance is used to create the checkpoint dir anyway and can therefore be reliably used to determine if it is local or not). The warning is only issued if the directory is not local, on top of the existing conditions. Author: pierre-borckmans <pierre.borckmans@realimpactanalytics.com> Closes #10392 from pierre-borckmans/SPARK-12440_CheckpointDir_Warning_NonLocal.

In the past Spark JDBC write only worked with technologies which support the following INSERT statement syntax (JdbcUtils.scala: insertStatement()): INSERT INTO $table VALUES ( ?, ?, ..., ? ) But some technologies require a list of column names: INSERT INTO $table ( $colNameList ) VALUES ( ?, ?, ..., ? ) This was blocking the use of e.g. the Progress JDBC Driver for Cassandra. Another limitation is that syntax 1 relies no the dataframe field ordering match that of the target table. This works fine, as long as the target table has been created by writer.jdbc(). If the target table contains more columns (not created by writer.jdbc()), then the insert fails due mismatch of number of columns or their data types. This PR switches to the recommended second INSERT syntax. Column names are taken from datafram field names. Author: CK50 <christian.kurz@oracle.com> Closes #10380 from CK50/master-SPARK-12010-2.

Accessing null elements in an array field fails when tungsten is enabled. It works in Spark 1.3.1, and in Spark > 1.5 with Tungsten disabled. This PR solves this by checking if the accessed element in the array field is null, in the generated code. Example: ``` // Array of String case class AS( as: Seq[String] ) val dfAS = sc.parallelize( Seq( AS ( Seq("a",null,"b") ) ) ).toDF dfAS.registerTempTable("T_AS") for (i <- 0 to 2) { println(i + " = " + sqlContext.sql(s"select as[$i] from T_AS").collect.mkString(","))} ``` With Tungsten disabled: ``` 0 = [a] 1 = [null] 2 = [b] ``` With Tungsten enabled: ``` 0 = [a] 15/12/22 09:32:50 ERROR Executor: Exception in task 7.0 in stage 1.0 (TID 15) java.lang.NullPointerException at org.apache.spark.sql.catalyst.expressions.UnsafeRowWriters$UTF8StringWriter.getSize(UnsafeRowWriters.java:90) at org.apache.spark.sql.catalyst.expressions.GeneratedClass$SpecificUnsafeProjection.apply(Unknown Source) at org.apache.spark.sql.execution.TungstenProject$$anonfun$3$$anonfun$apply$3.apply(basicOperators.scala:90) at org.apache.spark.sql.execution.TungstenProject$$anonfun$3$$anonfun$apply$3.apply(basicOperators.scala:88) at scala.collection.Iterator$$anon$11.next(Iterator.scala:328) at scala.collection.Iterator$$anon$11.next(Iterator.scala:328) at scala.collection.Iterator$class.foreach(Iterator.scala:727) at scala.collection.AbstractIterator.foreach(Iterator.scala:1157) ``` Author: pierre-borckmans <pierre.borckmans@realimpactanalytics.com> Closes #10429 from pierre-borckmans/SPARK-12477_Tungsten-Projection-Null-Element-In-Array. -

When creating extractors for product types (i.e. case classes and tuples), a null check is missing, thus we always assume input product values are non-null. This PR adds a null check in the extractor expression for product types. The null check is stripped off for top level product fields, which are mapped to the outermost `Row`s, since they can't be null. Thanks cloud-fan for helping investigating this issue!

[SPARK-11677][SQL][FOLLOW-UP] Add tests for checking the ORC filter creation against pushed down filters. https://issues.apache.org/jira/browse/SPARK-11677 Although it checks correctly the filters by the number of results if ORC filter-push-down is enabled, the filters themselves are not being tested. So, this PR includes the test similarly with `ParquetFilterSuite`. Since the results are checked by `OrcQuerySuite`, this `OrcFilterSuite` only checks if the appropriate filters are created. One thing different with `ParquetFilterSuite` here is, it does not check the results because that is checked in `OrcQuerySuite`.

An alternative solution for https://github.com/apache/spark/pull/10295 , instead of implementing json format for all logical/physical plans and expressions, use reflection to implement it in `TreeNode`. Here I use pre-order traversal to flattern a plan tree to a plan list, and add an extra field `num-children` to each plan node, so that we can reconstruct the tree from the list. example json: logical plan tree: ``` [ { "class" : "org.apache.spark.sql.catalyst.plans.logical.Sort", "num-children" : 1, "order" : [ [ { "class" : "org.apache.spark.sql.catalyst.expressions.SortOrder", "num-children" : 1, "child" : 0, "direction" : "Ascending" }, { "class" : "org.apache.spark.sql.catalyst.expressions.AttributeReference", "num-children" : 0, "name" : "i", "dataType" : "integer", "nullable" : true, "metadata" : { }, "exprId" : { "id" : 10, "jvmId" : "cd1313c7-3f66-4ed7-a320-7d91e4633ac6" }, "qualifiers" : [ ] } ] ], "global" : false, "child" : 0 }, { "class" : "org.apache.spark.sql.catalyst.plans.logical.Project", "num-children" : 1, "projectList" : [ [ { "class" : "org.apache.spark.sql.catalyst.expressions.Alias", "num-children" : 1, "child" : 0, "name" : "i", "exprId" : { "id" : 10, "jvmId" : "cd1313c7-3f66-4ed7-a320-7d91e4633ac6" }, "qualifiers" : [ ] }, { "class" : "org.apache.spark.sql.catalyst.expressions.Add", "num-children" : 2, "left" : 0, "right" : 1 }, { "class" : "org.apache.spark.sql.catalyst.expressions.AttributeReference", "num-children" : 0, "name" : "a", "dataType" : "integer", "nullable" : true, "metadata" : { }, "exprId" : { "id" : 0, "jvmId" : "cd1313c7-3f66-4ed7-a320-7d91e4633ac6" }, "qualifiers" : [ ] }, { "class" : "org.apache.spark.sql.catalyst.expressions.Literal", "num-children" : 0, "value" : "1", "dataType" : "integer" } ], [ { "class" : "org.apache.spark.sql.catalyst.expressions.Alias", "num-children" : 1, "child" : 0, "name" : "j", "exprId" : { "id" : 11, "jvmId" : "cd1313c7-3f66-4ed7-a320-7d91e4633ac6" }, "qualifiers" : [ ] }, { "class" : "org.apache.spark.sql.catalyst.expressions.Multiply", "num-children" : 2, "left" : 0, "right" : 1 }, { "class" : "org.apache.spark.sql.catalyst.expressions.AttributeReference", "num-children" : 0, "name" : "a", "dataType" : "integer", "nullable" : true, "metadata" : { }, "exprId" : { "id" : 0, "jvmId" : "cd1313c7-3f66-4ed7-a320-7d91e4633ac6" }, "qualifiers" : [ ] }, { "class" : "org.apache.spark.sql.catalyst.expressions.Literal", "num-children" : 0, "value" : "2", "dataType" : "integer" } ] ], "child" : 0 }, { "class" : "org.apache.spark.sql.catalyst.plans.logical.LocalRelation", "num-children" : 0, "output" : [ [ { "class" : "org.apache.spark.sql.catalyst.expressions.AttributeReference", "num-children" : 0, "name" : "a", "dataType" : "integer", "nullable" : true, "metadata" : { }, "exprId" : { "id" : 0, "jvmId" : "cd1313c7-3f66-4ed7-a320-7d91e4633ac6" }, "qualifiers" : [ ] } ] ], "data" : [ ] } ] ``` Author: Wenchen Fan <wenchen@databricks.com> Closes #10311 from cloud-fan/toJson-reflection.
