expose calculate midrange for token in jmx
------------------------------------------
Key: CASSANDRA-2917
URL: https://issues.apache.org/jira/browse/CASSANDRA-2917
Project: Cassandra
Issue Type: Improvement
Reporter: Jackson Chung
Priority: Minor
currently there is no easy way to get midrange, especially for OPP. For
simplicity, you could call OrderPreservingPartitioner.midpoint(Token, Token),
that gives you a rough estimate (and you'd still need to remove non-utf8
characters.)
A more accurate but difficult way is to sample the keys in that range and pick
the midpoint of those. We should expose that via jmx, because without this,
supporting OPP w/o this is quite challenging.
