------------------------------------------
Summary: Provide retry mechanism for the blocks which were failed
while moving its storage at DNs
Key: HDFS-11029
URL: https://issues.apache.org/jira/browse/HDFS-11029
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode
Affects Versions: HDFS-10285
Reporter: Uma Maheswara Rao G
Assignee: Uma Maheswara Rao G
When DN co-ordinator finds some of blocks associated to trackedID could not be
moved its storages, due to some errors.Here retry may work in some cases,
example if target node has no space. Then retry by finding another target can
work.
So, based on the movement result flag(SUCCESS/FAILURE) from DN Co-ordinator,
NN would retry by scanning the blocks again.
