> This jira is a follow-up task of HDFS-10884. As part of HDFS-10884 jira, it
> is providing a mechanism to collect all the success/failed block movement
> results at the {{co-ordinator datanode}} side. Now, the idea of this jira is
> to discuss an efficient way to report these success/failed block movement
> results to namenode, so that NN can take necessary action based on this
> information.
