> CommitSession has an integer sequence number that could possibly overflow if a tablet does 1 billion minor compactions on the same tablet server.  It would be nice to either change this to a long or check if the interger has overflowed after incrementing.  This problem was identified while looking int ACCUMULO-4777, there are some comments there with background information.
