Major Description
I was regenerating output as part of the merge:

and the test JVM ran out of threads:
java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:713) at org.apache.hadoop.util.Shell.runCommand(Shell.java:521) at org.apache.hadoop.util.Shell.run(Shell.java:455) at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:702) at org.apache.hadoop.util.Shell.execCommand(Shell.java:791) at org.apache.hadoop.util.Shell.execCommand(Shell.java:774) at org.apache.hadoop.fs.FileUtil.execCommand(FileUtil.java:1097) at org.apache.hadoop.fs.RawLocalFileSystem$DeprecatedRawLocalFileStatus.loadPermissionInfo(RawLocalFileSystem.java:572) at org.apache.hadoop.fs.RawLocalFileSystem$DeprecatedRawLocalFileStatus.getPermission(RawLocalFileSystem.java:547) at org.apache.hadoop.fs.ProxyFileSystem.swizzleFileStatus(ProxyFileSystem.java:61) at org.apache.hadoop.fs.ProxyFileSystem.getFileStatus(ProxyFileSystem.java:265) at org.apache.hadoop.fs.FilterFileSystem.getFileStatus(FilterFileSystem.java:397) at org.apache.hadoop.fs.FileSystem.exists(FileSystem.java:1398) at org.apache.hadoop.hive.ql.QTestUtil.clearTablesCreatedDuringTests(QTestUtil.java:578) at org.apache.hadoop.hive.ql.QTestUtil.clearTestSideEffects(QTestUtil.java:606) at org.apache.hadoop.hive.cli.TestSparkCliDriver.setUp(TestSparkCliDriver.java:66)
thus there is a thread-leak somewhere in the test framework or in our RSC integration.
