Cassandra 2.0.4 cannot start

ERROR [main] 2014-02-05 16:19:24,375 CassandraDaemon.java (line 478) Exception encountered during startup
java.lang.IllegalStateException: Unfinished compactions reference missing sstables. This should never happen since compactions are marked finished before we start removing the old sstables.


解决：mkdir /opt/cassandra/compactions_in_progress.20140205; mv /opt/cassandra/data/system/compactions_in_progress/* /opt/cassandra/compactions_in_progress.20140205/
