> Assure thread safety
> --------------------
>                 Key: HBASE-6186
>                 URL: https://issues.apache.org/jira/browse/HBASE-6186
>             Project: HBase
>          Issue Type: Sub-task
>          Components: security
>    Affects Versions: 0.94.0, 0.94.1, 0.95.2
>            Reporter: Andrew Purtell
>              Labels: security
> Check data structures for necessary thread safety.
> One known issue is as follows:
> In TableAuthManager, we need to deal with concurrent grants and revokes now that ADMIN
permission can be delegated to perhaps multiple users.
> Consider using a ReadWriteLock to protect for update. The current data structure is an
array multimap. It is also possible to obtain a synchronized multimap from Guava with Multimaps#synchronizedListMultimap
but by far the most common access is read access, and concurrent read access is fine.
