The findbugs warning (to do with System.exit) is expected. Not sure why it is flagging two warnings.. > Delegation token cancellation shouldn't hold global JobTracker lock > ------------------------------------------------------------------- > > Key: MAPREDUCE-2452 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2452 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: jobtracker > Affects Versions: 0.22.0 > Reporter: Devaraj Das > Assignee: Devaraj Das > Fix For: 0.23.0 > > Attachments: cancel-delegation-token-fix-trunk.patch, cancel-delegation-token-fix.patch, cancel-delegation-token-fix.patch, cancel-delegation-token-fix.patch > > > Currently, when the JobTracker cancels a job's delegation token (at the end of the job), it holds the global lock.
