Jeff Jirsa commented on CASSANDRA-12499:
----------------------------------------
Branch here:
https://github.com/jeffjirsa/cassandra/commit/e7cb6c3409b889174d32c4eec9f60da380f39d3d
Believe patch applies cleanly to 3.0 -> trunk (or it did a few days ago when
written)
testall shows no failures:
http://cassci.datastax.com/job/jeffjirsa-cassandra-12499-testall/lastBuild/testReport/
dtest shows one failure that appears unrelated:
