Subject [jira] Reopened: (CASSANDRA-1079) Cache capacity settings done via nodetool get reset on memtable flushes

Jonathan Ellis reopened CASSANDRA-1079:
---------------------------------------


Oh.  Sometimes I need to read things twice -- yes, it's a bug if it's not persisting between
flushes.  (I'm saying that it's not supposed to persist b/t restarts, unless you change the
conf file too.)

> In an experiment we set cache capacities via nodetool. The config file had the KeyCache
for this CF at 1000000, we set the RowCache to 10000000 via nodetool.
> The next time we flushed a memtable for that CF, the cache capacity settings got reverted
to what is in the conf file. We repeated the experiment with the same results.
