Thanks for kicking jenkins [~jojochuang]. Last rerun was after HDFS-12458 which fixed the
flaky test. Failures unrelated.

> Re-encryption should handle task cancellation and progress tracking better in general.
> In a recent internal report, a canceled re-encryption could lead to the progress of the
zone being 'Processing' forever. Sending a new cancel command would make it complete, but
new re-encryptions for the same zone wouldn't work because the canceled future is not removed.
> This jira proposes to fix that, and enhance the currently handling so new command would
start from a clean state.
