-------------------------------------------
> 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.
