Rohit Kochar commented on HDFS-4581:
------------------------------------
We are facing an issue in which most of checkDiskError() invocations are
happening due to network related exceptions in
BlockReciever$PacketResponder.run() and DataNode$DataTransfer.run().
Since the current code has a common catch clause for all types of exceptions
hence even for network related IO Exceptions chedkDiskError() in executed which
lead to check storm thereby slowing the datanode.
> DataNode#checkDiskError should not be called on network errors
