    Description

      Presently DFSOutputStream#streamer object reference is accessed inconsistently with respect to synchronization. It would be good to improve this part. This has been noticed when implementing the erasure coding feature.

      Please refer the related discussion thread in the jira HDFS-8294 for more details.
