Sean Owen updated SPARK-20243: ------------------------------ Comment: was deleted (was: This needs detail to be a JIRA.) > DebugFilesystem.assertNoOpenStreams thread race > ----------------------------------------------- > > Key: SPARK-20243 > URL: https://issues.apache.org/jira/browse/SPARK-20243 > Project: Spark > Issue Type: Bug > Components: Tests > Affects Versions: 2.2.0 > Reporter: Bogdan Raducanu > > Introduced by SPARK-19946. > DebugFilesystem.assertNoOpenStreams gets the size of the openStreams > ConcurrentHashMap and then later, if the size was > 0, accesses the first > element in openStreams.values. But, the ConcurrentHashMap might be cleared by > another thread between getting its size and accessing it, resulting in an > exception when trying to call .head on an empty collection. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
