-----------------------------------
Summary: HiveServer2 CancelOperation does not work for long
running queries
Key: HIVE-7198
URL: https://issues.apache.org/jira/browse/HIVE-7198
Project: Hive
Issue Type: Bug
Components: HiveServer2
Affects Versions: 0.12.0
Reporter: Romain Rigaux
Sending the CancelOperation() call does not always stop the query and its
related MapReduce jobs.
e.g. from https://issues.cloudera.org/browse/HUE-2144
{code}
I guess you're right. But the strange thing is that the canceled query shows in
job browser as 'Running' and the percents go up - 0%, 50%, then the job is
failed.
How does the cancelling actually work? Is it like the hadoop kill command? It
seems to me like it works until certain phase of map reduce is done.
And another thing - after cancelling the job in Hue I can kill it with hadoop
job -kill job_<id>. If it was killed already, it would show "no such job".
{code}
