Yiqun Lin commented on HDFS-12675:
----------------------------------
I am thinking one corner case leading for this:
# {{LeaseNotFoundException}} or {{LeaseExpiredException}} is thrown in loop
{{for (T resource : activeLeases.keySet()) {}}.
# Then the {{sleepTime}} used in {{while}} loop doesn't get a correct value,
then program sleep for {{Long.MAX_VALUE}} time.Remaining leases cannot be
released.
