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

             Summary: Erasure Coding: optimize client writing by making the writing of data and parity  concurrently
                 Key: HDFS-8529
                 URL: https://issues.apache.org/jira/browse/HDFS-8529
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Li Bo
            Assignee: Li Bo


HDFS-8425 shows the client writing is not very efficient currently. One factor is that  when data buffers are full, client suspends until the parities are encoded and written. This sub task tries to make the two writings concurrently to enhance the efficiency.
