             Summary: Move IO operations out of locking in OpenFileCtx
                 Key: HDFS-4971
                 URL: https://issues.apache.org/jira/browse/HDFS-4971
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Jing Zhao
            Assignee: Jing Zhao


Currently some IO operations (such as writing data to HDFS and dumping to local disk) in OpenFileCtx may hold a lock which can block processing incoming writing requests. This jira aims to optimize OpenFileCtx and move the IO operations out of the locking.
