---------------------------------
Summary: Templeton launcher job should reconnect to the running
child job on its task retry when RMHA is enabled
Key: HIVE-10959
URL: https://issues.apache.org/jira/browse/HIVE-10959
Project: Hive
Issue Type: Bug
Components: WebHCat
Affects Versions: 0.15.0
Reporter: Ivan Mitic
Assignee: Ivan Mitic
Currently, Templeton launcher kills all child jobs (jobs tagged with the parent
job's id) upon task retry.
Upon templeton launcher task retry, templeton should reconnect to the running
job and continue tracking its progress that way.
This logic cannot be used for all job kinds (e.g. for jobs that are driven by
the client side like regular hive). However, for MapReduceV2, and possibly Tez
and HiveOnTez, this should be the default.
