-------------------------------------

[~linyiqun] Thanks for fixing this issue. [~vagarychen] Thanks for committing this. [~nandakumar131] Thanks for filing this issue. 

Since this is a performance improvement, I am curious how much this change improves the performance by .. Say for 4KB files, 8KB and say 1MB files. I am just curious to see the improvement, Would any of you have this number which you can share ?

> 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.
