[jira] [Created] (HDFS-9050) updatePipeline RPC call should only take new GS as input

Zhe Zhang created HDFS-9050:
-------------------------------

             Summary: updatePipeline RPC call should only take new GS as input
                 Key: HDFS-9050
                 URL: https://issues.apache.org/jira/browse/HDFS-9050
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.7.1
            Reporter: Zhe Zhang
            Assignee: Zhe Zhang


The only usage of the call is in {{DataStreamer#updatePipeline}}, where {{newBlock}} differs from current {{block}} only in GS.

Basically the RPC call is not supposed to update the {{poolID}}, {{ID}}, and {{numBytes}} of the block on NN.
