2011-07-06 Thread Scott Dworkis
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 node
