Subject [jira] [Created] (HDFS-7463) Simplify FSNamesystem#getBlockLocationsUpdateTimes
Date Tue, 02 Dec 2014 07:14:12 GMT
Haohui Mai created HDFS-7463:
--------------------------------

             Summary: Simplify FSNamesystem#getBlockLocationsUpdateTimes
                 Key: HDFS-7463
                 URL: https://issues.apache.org/jira/browse/HDFS-7463
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Haohui Mai
            Assignee: Haohui Mai


Currently {{FSNamesystem#getBlockLocationsUpdateTimes}} holds the read lock to access the
blocks. It releases the read lock and then acquires the write lock when it needs to update
the access time of the {{INode}}.

This jira proposes to move the responsibility of the latter steps to the caller to simplify
the code.
