Description

Reproduce Steps

1. Launch an ozone cluster
2. Create a volume via commandline

   hdfs oz -createVolume http://ozone1.fyre.ibm.com:9864/volume-wwei-0 -user root
   

it failed with following error

SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container

This was because keySpaceManagerClient in ObjectStoreHandler currently is not properly initiated, it should be using ProtobufRpcEngine instead of WritableRpcEngine which is deprecated.
