----------------------------------
Hi [~anu], I did a simple test in my local. I wrote a unit test that using oz
shell command to put 2k files in old/new put key way. And calculate the total
elapsed time of these two ways. I found the new way is faster than the old way
a little. The old way costs 136s while new way costs 116s. But I think if the
cluster is busy enough, the new way will make more sense.

> With current implementation multiple RPC calls are made for each put/get key
> ozone shell call
> {code:title=org.apache.hadoop.ozone.web.ozShell.keys.PutKeyHandler#execute}
> OzoneVolume vol = client.getVolume(volumeName);
> OzoneBucket bucket = vol.getBucket(bucketName);
> bucket.putKey(keyName, dataFile);
> {code}
> {code:title=org.apache.hadoop.ozone.web.ozShell.keys.GetKeyHandler#execute}
> OzoneVolume vol = client.getVolume(volumeName);
> OzoneBucket bucket = vol.getBucket(bucketName);
> bucket.getKey(keyName, dataFilePath);
> {code}
> This can be optimized.
