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

             Summary: Create Version File in Datanode
                 Key: HDDS-97
                 URL: https://issues.apache.org/jira/browse/HDDS-97
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Bharat Viswanadham


Create a versionFile in dfs.datanode.dir/hdds/ path.

The content of the versionFile:
 # scmUuid
 # CTime
 # layOutVersion

When datanodes makes a request for SCMVersion, in this response we send scmUuid.

With this response, we should be able to create version file on the datanode.
