Walter Su commented on HDFS-8411:
---------------------------------
I think this metric is unnecessary. Block replication has no bytes count
either. You can keep this if you want. Btw, {{ecBytesRead}} can be easily
mistaken for the bytes read by Client.
> Add bytes count metrics to datanode for ECWorker
