> Project: Hadoop Common
> Issue Type: Bug

> Currently, DelegationTokenRenewer is not singleton.
> Each filesystem using it spawns its own DelegationTokenRenewer. Also, they
> don't stop the Renewer leading to other problems.
> A single DelegationTokenRenewer should be sufficient for all FileSystems.
