Description

In our multi-tenant hbase cluster, we found that there are over 1M znodes under the acl node. The reason is that users create and delete tables with different names frequently. The acl notify znode are left there after the tables are deleted.

Simple solution is that deleting acl notify znode of table in AccessController when deleting the table.
