[jira] [Created] (HDFS-16633) Reserved Space For Replicas is not released

Prabhu Joseph created HDFS-16633:
------------------------------------

             Summary: Reserved Space For Replicas is not released 
                 Key: HDFS-16633
                 URL: https://issues.apache.org/jira/browse/HDFS-16633
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
    Affects Versions: 3.1.2
            Reporter: Prabhu Joseph
            Assignee: Prabhu Joseph


Have found the Reserved Space For Replicas is not released on a Cx Prod cluster. There are few fixes like HDFS-9530 and HDFS-8072 but still the issue is not completely fixed. Have tried to debug the root cause but this will take lot of time as it is Cx Prod Cluster. 

But we have an easier way to fix the issue completely by releasing any remaining reserved space from BlockReceiver#close which is initiated by DataXceiver#writeBlock finally.
