--------------------------------
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.
