Rohit Agarwal commented on HIVE-10569: -------------------------------------- Thank you for committing this [~ashutoshc]. We have done some work around cleaning up non-threadsafe code in Hive, will ask around to see if HIVE-10404 can be a problem for us. Thanks for the heads up! > Hive CLI gets stuck when hive.exec.parallel=true; and some exception happens > during SessionState.start > ------------------------------------------------------------------------------------------------------ > > Key: HIVE-10569 > URL: https://issues.apache.org/jira/browse/HIVE-10569 > Project: Hive > Issue Type: Bug > Affects Versions: 0.13.1, 1.2.0, 1.1.0 > Reporter: Rohit Agarwal > Assignee: Rohit Agarwal > Priority: Critical > Fix For: 1.3.0 > > Attachments: HIVE-10569.patch > > > The CLI gets stuck in the loop in [DriverContext.pollFinished | > https://github.com/apache/hive/blob/release-1.1.0/ql/src/java/org/apache/hadoop/hive/ql/DriverContext.java#L108] > when some {{TaskRunner}} which has completed has not been marked as > non-running. > This can happen when there is exception in [SessionState.start | > https://github.com/apache/hive/blob/release-1.1.0/ql/src/java/org/apache/hadoop/hive/ql/exec/TaskRunner.java#L74] > which is called from {{TaskRunner.run}}. > This happened with us when we were running with {{hive.exec.parallel=true}}, > {{hive.execution.engine=tez}} and Tez wasn't correctly setup. > In this case the CLI printed the exception and then got hung (No prompt.) > A simple fix is to call {{result.setRunning(false);}} in the {{finally}} > block of {{TaskRunner.run}} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
