Mingliang Liu created HDFS-9467:
-----------------------------------

             Summary: Fix data race accessing writeLockHeldTimeStamp in FSNamesystem
                 Key: HDFS-9467
                 URL: https://issues.apache.org/jira/browse/HDFS-9467
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
            Reporter: Mingliang Liu
            Assignee: Mingliang Liu


This is a followup of [HDFS-9145].

Actually the value of {{writeLockInterval}} should be captured within the lock. The current code has a race on {{writeLockHeldTimeStamp}}. Thanks to [~jingzhao] for reporting this.
