Andrew Purtell resolved HBASE-6186. ----------------------------------- Resolution: Invalid > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
