[jira] [Created] (HDFS-16620) Improve msync performance by a separate RPC server

Yongpan Liu created HDFS-16620:
----------------------------------

             Summary: Improve msync performance by a separate RPC server
                 Key: HDFS-16620
                 URL: https://issues.apache.org/jira/browse/HDFS-16620
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Yongpan Liu


ClientProtocol#msync is invoked frequently in clusters where the Observer is enabled. When NameNode is heavily loaded, the average response time of msync increases, which can affect Observer Read efficiency. We can split out a separate RPC server just like HDFS-9311.
