I looked at Filter one more time this morning - it doesn't have method which returns the row in which the Filter is interested in.
Since each of your RowFilter instances may be constructed from unique objects in memory (though they can be considered equal after byte wise comparison), we need more formal way of defining equality - which is required for implementing Set. In this regard, we should revisit HBASE-19008 <https://issues.apache.org/jira/browse/HBASE-19008> first.
