couple questions about commitlogs and the nodetool drain operator:
* in 0.6, after invoking a drain, the commitlog directory would be empty.
in 0.8, it seems to contain 2 files, a 44 byte .header file and 270 byte
.log file. do these indicate a fully drained commitlog?
* i have a couple nodes for which the commitlogs do not seem to be
draining at all... they remain several hundred k or meg in size. are they
corrupt? if the data is not precious, is there some way to clear and reset
them to work around this?
also, i see this in system.log:
/data/var/log/cassandra/system.log.1:DEBUG [COMMIT-LOG-WRITER] 2011-07-06
11:04:10,076 CommitLog.java (line 473) Not safe to delete commit log
