> Token state eviction should access the keystore file less frequently

> Key: KNOX-2375
> URL: https://issues.apache.org/jira/browse/KNOX-2375
> Project: Apache Knox
> Issue Type: Bug
> Components: Server
> Affects Versions: 1.4.0
> Reporter: Philip Zampino
> Assignee: Philip Zampino
> Priority: Major
> Time Spent: 2.5h
> Remaining Estimate: 0h
>
> When the AliasBasedTokenStateService is employed, the TokenStateService
> reaper loads the keystore file (via the AliasService and KeyStoreService)
> very frequently.
> # It queries all the token-state-related aliases
> # For every token ID
> ## Looks up the token again (validateToken())
> ## Looks up the the token expiration
> ## Removes the token expiration alias
> ## Removes the token max lifetime alias
> This means the KeyStoreService loads the keystore file (1 + 2-to-4-per-token)
> times every eviction interval (default 5 minutes). That means, if there are
> 100 expired tokens and 100 unexpired tokens, the reaper will load the
> keystore file 601 times in one iteration.
> As the keystore file size increases, the already poor performance of loading
> this file degrades even more to the point that the token state reaper can
> consume 100% of the CPU.
> The reaper should operate on the in-memory token state as much as possible,
> and even remove expired token state in bulk (loading / writing the keystore
> file once for all).
