    Description

      RECENT HISTORY

      http://spark-tests.appspot.com/test-details?suite_name=org.apache.spark.sql.FileBasedDataSourceSuite&test_name=%28It+is+not+a+test+it+is+a+sbt.testing.SuiteSelector%29

       


      We're seeing multiple failures in FileBasedDataSourceSuite in spark-branch-2.3-test-sbt-hadoop-2.7:

      org.scalatest.exceptions.TestFailedDueToTimeoutException: The code passed to eventually never returned normally. Attempted 15 times over 10.012158059999999 seconds. Last failure message: There are 1 possibly leaked file streams..
      

      Here's the full history: https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-branch-2.3-test-sbt-hadoop-2.7/189/testReport/org.apache.spark.sql/FileBasedDataSourceSuite/history/

      From a very quick look, these failures seem to be correlated with https://github.com/apache/spark/pull/20479 (cc Dongjoon Hyun) as evident from the following stack trace (full logs here):

      [info] - Enabling/disabling ignoreMissingFiles using orc (648 milliseconds)
      15:55:58.673 WARN org.apache.spark.scheduler.TaskSetManager: Lost task 0.0 in stage 61.0 (TID 85, localhost, executor driver): TaskKilled (Stage cancelled)
      15:55:58.674 WARN org.apache.spark.DebugFilesystem: Leaked filesystem connection created at:

      	at org.apache.spark.sql.execution.datasources.orc.OrcColumnarBatchReader.initialize(OrcColumnarBatchReader.java:138)
      

      Also, while this might be just a false correlation but the frequency of these test failures have increased considerably in https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-branch-2.3-test-sbt-hadoop-2.7/ after https://github.com/apache/spark/pull/20562 (cc Feng Liu) was merged.

      The following is Parquet leakage.
