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

             Summary: Ozone: Ensure KSM is initiated using ProtobufRpcEngine
                 Key: HDFS-11958
                 URL: https://issues.apache.org/jira/browse/HDFS-11958
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
            Reporter: Weiwei Yang
            Assignee: Weiwei Yang
            Priority: Critical


Reproduce Steps

# Launch an ozone cluster
# Create a volume via commandline
{code}
hdfs oz -createVolume http://ozone1.fyre.ibm.com:9864/volume-wwei-0 -user root
{code}

it failed with following error

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