Siddharth Wagle created HDDS-2242:
-------------------------------------

             Summary: Avoid unnecessary rpc needed to discover the pipeline leader 
                 Key: HDDS-2242
                 URL: https://issues.apache.org/jira/browse/HDDS-2242
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
          Components: Ozone Client
    Affects Versions: 0.5.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 0.5.0


HDDS-1868 adds the leaderID to pipeline protobuf. Client should use this to stream requests directly to the leader vs current randomly choosing one of the datanodes in the pipeline and relying on the follower to tell the client which node is the leader.
