Rushabh S Shah updated HDFS-7916:
---------------------------------
Attachment: HDFS-7916-1.patch
This patch simply ignores the block when BPServiceActor receives the
RemoteException from namenode.
The namenode got the report once and then it chose not to process that request.
So it doesn't make much sense to add that request again to queue.
> 'reportBadBlocks' from datanodes to standby Node BPServiceActor goes for
> infinite loop
