Mukul Kumar Singh commented on HDDS-339:
----------------------------------------

Thanks for working on this [~shashikant]. Please find my review comments as 
following.

1) DatanodeContainerProtocol.proto:311, getCommittedBlockLength-> 
committedBlockLength
2) KeyValueHandler:43, Unused import
3)  KeyValueHandler:438, I feel the length can be returned as part of 
commitKey, once the key has been committed successfully, the length can be 
returned.
4) KeyUtils:156, there is a unused variable here, I feel this can be removed
5) KeyUtils:140, putKeyResposne-> putKeyResponse
6) KeyUtils:130, returns putkey response success
7) KeyUtils:134, getPutKeyResponseSuccess -> putKeyResponseSuccess
8) KeyUtils:194, msg is a unused field


> Add block length and blockId in PutKeyResponse
