-------------------------------------

             Summary: Assure thread safety
                 Key: HBASE-6186
                 URL: https://issues.apache.org/jira/browse/HBASE-6186
             Project: HBase
          Issue Type: Sub-task
            Reporter: Andrew Purtell


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.
