-------------------------------------------
Summary: MergeFileTask needs to be interruptible
Key: HIVE-17273
URL: https://issues.apache.org/jira/browse/HIVE-17273
Project: Hive
Issue Type: Bug
Affects Versions: 2.2.0, 3.0.0
Reporter: Mithun Radhakrishnan
Assignee: Mithun Radhakrishnan
This is an extension to the work done in HIVE-16820 (which made {{TezTask}}
exit correctly when the job is cancelled.)
If a Hive job involves a {{MergeFileTask}} (say {{ALTER TABLE ... PARTITION ...
CONCATENATE}}), and is cancelled *after* the merge-task has kicked off, then
the merge-task might not be cancelled, and might run through to completion.
The code should check if the merge-job has already been scheduled, and cancel
it if required.
