>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: resourcemanager
>    Affects Versions: 3.1.0
>            Reporter: Wilfred Spiegelenburg
>            Assignee: Wilfred Spiegelenburg
>            Priority: Major

> When the RM state store is restored expired delegation tokens are restored and added
to the system. These expired tokens do not get cleaned up or removed. The exact reason why
the tokens are still in the store is not clear. We have seen as many as 250,000 tokens in
the store some of which were 2 years old.
> This has two side effects:
> * for the zookeeper store this leads to a jute buffer exhaustion issue and prevents the
RM from becoming active.
> * restore takes longer than needed and heap usage is higher than it should be
> We should not restore already expired tokens since they cannot be renewed or used.
