[jira] [Updated] (HIVE-10569) Hive CLI gets stuck when
hive.exec.parallel=true; and some exception happens during
SessionState.start
[ https://issues.apache.org/jira/browse/HIVE-10569?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
hao updated HIVE-10569:
-----------------------
Description:
_强调文本_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}}
