> Key: HADOOP-9549
> URL: https://issues.apache.org/jira/browse/HADOOP-9549
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 2.0.4-alpha
> Reporter: Kihwal Lee
> Assignee: Daryn Sharp
> Priority: Blocker
>
> When close() is called via fs shoutdown hook, the synchronized method,
> removeRenewAction() hangs. This is because DelegationTokenRenewer calls
> DelayQueue.take() inside a synchronized block. Since this is a blocking call,
> it hangs forever.
