Nandakumar commented on HDFS-12519:
-----------------------------------
[~linyiqun], The reason for having {{leaseMonitorThread.interrupt()}} is
because we support custom timeout in {{acquire(T resource, long timeout)}},
custom timeout value can be set less than default timeout. In this case we need
to re-calculate the sleep time in {{LeaseMonitor}}, because new lease might
have less {{remainingTime}} than the one we calculate previously.

> Many objects, including Containers and pipelines can time out during creating
> process. We need a way to track these timeouts. This lease Manager allows SCM
> to hold a lease on these objects and helps SCM timeout waiting for creating
> of these objects.
