Hi,
I have this stack trace in the logs of Cassandra server (v2.1)
{code}
ERROR [CompactionExecutor:14] 2014-10-06 23:32:02,098 CassandraDaemon.java:166

{code}
It may not be critical because this error occured in the AutoSavingCache.
However the line 475 is about the CFMetaData so it may hide bigger issue...
{code}
474 CFMetaData cfm =
Schema.instance.getCFMetaData(key.desc.ksname, key.desc.cfname);
475 cfm.comparator.rowIndexEntrySerializer().serialize(entry, out);
{code}
Regards,
Eric
