Sahil Takiar created HIVE-18214: ----------------------------------- Summary: Flaky test: TestSparkClient Key: HIVE-18214 URL: https://issues.apache.org/jira/browse/HIVE-18214 Project: Hive Issue Type: Sub-task Components: Spark Reporter: Sahil Takiar Assignee: Sahil Takiar
Looks like there is a race condition in {{TestSparkClient#runTest}}. The test creates a {{RemoteDriver}} in memory, which creates a {{JavaSparkContext}}. A new {{JavaSparkContext}} is created for each test that is run. There is a race condition where the {{RemoteDriver}} isn't given enough time to shutdown, so when the next test starts running it creates another {{JavaSparkContext}} which causes an exception like {{org.apache.spark.SparkException: Only one SparkContext may be running in this JVM (see SPARK-2243)}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
