Description

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.
