Andrew Purtell commented on HBASE-6096:
---------------------------------------
bq. In TableAuthManager, we may need to maintain thread-safe data structures.
So let's consider using a
[ReadWriteLock|http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/locks/ReadWriteLock.html]
to protect for update. It is also possible to obtain a synchronized multimap
with
[Multimaps#synchronizedListMultimap|http://google-collections.googlecode.com/svn/trunk/javadoc/com/google/common/collect/Multimaps.html#synchronizedListMultimap(com.google.common.collect.ListMultimap)]
but by far the most common access is read access, and concurrent read access
is fine.
