--------------------------------
Summary: Re-encryption should handle task cancellation and
progress better
Key: HDFS-12518
URL: https://issues.apache.org/jira/browse/HDFS-12518
Project: Hadoop HDFS
Issue Type: Bug
Components: encryption
Affects Versions: 3.0.0-beta1
Reporter: Xiao Chen
Assignee: Xiao Chen
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.
