[jira] [Created] (HDFS-13387) Make multi-thread access class thread safe

maobaolong created HDFS-13387:
---------------------------------

             Summary: Make multi-thread access class thread safe
                 Key: HDFS-13387
                 URL: https://issues.apache.org/jira/browse/HDFS-13387
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
    Affects Versions: 3.2.0
            Reporter: maobaolong
            Assignee: maobaolong


This jira will lead us to make the class as BlockInfoContiguous thread-safe, then, we should not use the NameSystemLock to lock the full flow. This just a base step to achieve the plan of HDFS-8966
