--------------------------------
Summary: Allow for tablet copy cancellation
Key: KUDU-1729
URL: https://issues.apache.org/jira/browse/KUDU-1729
Project: Kudu
Issue Type: Bug
Components: consensus, tablet
Reporter: Mike Percy
Allow for tablet copy cancellation
* Useful in the case that we begin a tablet copy to a new replica, a previous
replica “returns from the dead”, and so we may decide we don’t want to continue
with the tablet copy anymore
* We may also want to cancel a tablet copy that has gotten stuck or has been
extremely slow and has hit some kind of timeout.
* This would also allow us to potentially speculatively copy a tablet to
multiple replicas, only to cancel or delete the slowest one.
