Todd Lipcon updated HDFS-2577:
------------------------------
Attachment: hdfs-2577.txt
Attached patch changes back to the trunk behavior: only start the DT manager if
security is enabled.
Also fixed another related bug I noticed while testing this fix -- with
HDFS-2301 the lease manager stop was always timing out, since it was looping on
namesystem.isRunning() which continues to be true even in standby mode. Added a
flag to LeaseManager to decide whether the monitor should run.
Tests seem to be passing now.
