Hi,   We are running with acl error in HBase. One of our user named "x" is part of the group called "A". And "A" is part of another group "B". Now Group "B" have access to a table "p" in Hbase.   When user "x" is trying to access table "p", he is getting error as access denied.   I want to know whether hbase acls supports subgroup members or only direct group members only will have access?     Thanks Srini ...
