[jira] [Created] (HIVE-17273) MergeFileTask needs to be interruptible

Mithun Radhakrishnan created HIVE-17273:
-------------------------------------------

             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.
