Subject [jira] [Created] (ACCUMULO-4795) cancel bulk import in progress
Date Thu, 01 Feb 2018 19:17:00 GMT
Mark Owens created ACCUMULO-4795:

             Summary: cancel bulk import in progress
                 Key: ACCUMULO-4795
             Project: Accumulo
          Issue Type: Sub-task
          Components: master, tserver
            Reporter: Mark Owens

Accumulo currently provides mechanisms to initiate bulk imports and to list bulk imports in
progress. Scheduling of bulk import requests is not entirely deterministic, and most of the
execution of a bulk-import request is done in a non-preemptable manner. As such, any bulk
import which takes very long to complete can block bulk imports with higher operational priority
for significant periods.

To better support bulk-import-heavy applications, it would be nice if Accumulo would offer
additional mechanisms for controlling the scheduling and execution of bulk imports

One such feature would be the ability to cancel bulk import in progress.

If possible, canceling a partially completed bulk import request should result in a rollback
of changes. That is, a bulk import should either succeed or make no changes.
