Prabhu Joseph updated HDFS-16633:
---------------------------------
Description:
Have found the Reserved Space For Replicas is not released on some cases in 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.
