Description

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.
