---------------------------------
Summary: Oozie should pass mapreduce.job.tags to Beeline in Hive2
action
Key: OOZIE-3643
URL: https://issues.apache.org/jira/browse/OOZIE-3643
Project: Oozie
Issue Type: Task
Affects Versions: 5.2.1
Reporter: Dénes Bodó
Currently if we start a Hive2 action which starts a Tez child job and that runs
for long and then we try to kill the Oozie workflow which started that Hive2
action we experience that the started Tez child job remains running.
To solve this problem Hive on Tez configurations should be set:
*hive.server2.tez.initialize.default.sessions=false* and Oozie should pass the
launcher job's tag to beeline to be able to find the Tez child job. In Oozie we
could do something like:
{code:java}
arguments.add("--hiveconf");
arguments.add("hive.query.tag=" + actionConf.get(MAPREDUCE_JOB_TAGS)); {code}
in Hive2Main class.
As I experienced in my test environment when I did killed such a workflow it
killed the Tez child job too but unfortunately a new instance of my workflow
wasn't able to start the Hive query, the launcher job stuck.
