>
> Recently saw a ResourceManager go into heavy GC. Heap dump showed that there
> were millions of delegation tokens on the heap. It looks like most of them
> belonged to the appTokens map in DelegationTokenRenewer. When an app
> completes and tokens are removed for it, I noticed that the appTokens entry
> for the app is not cleaned up if tokens were shared with other active apps.
