xuzq created HDFS-14710:
---------------------------

             Summary: RBF：Improve some RPC performances
                 Key: HDFS-14710
                 URL: https://issues.apache.org/jira/browse/HDFS-14710
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: rbf
            Reporter: xuzq


We can improve some RPC performance if the extendedBlock is not null.

Such as addBlock, getAdditionalDatanode and complete.

Since HDFS encourages user to write large files, so the extendedBlock is not null in most case.

In the scenario of Multiple Destination and large file, the effect is more obvious.
