> 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.
