-------------------------------------------

             Summary: Excess replicas will not be deleted until all storages's FBR received
after failover
                 Key: HDFS-11146
                 URL: https://issues.apache.org/jira/browse/HDFS-11146
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Brahma Reddy Battula
            Assignee: Brahma Reddy Battula


Excess replicas will not be deleted until all storages's FBR received after failover.

Thinking following soultion can help.

 *Solution:* 

I think after failover, As DNs aware of failover ,so they can send another block report (FBR)
irrespective of interval.May be some shuffle can be done, similar to initial delay.
