from NEWS.txt: Upgrading --------- - 0.7.1 and 0.7.2 shipped with a bug that caused incorrect row-level bloom filters to be generated when compacting sstables generated with earlier versions. This would manifest in IOExceptions during column name-based queries. 0.7.3 provides "nodetool scrub" to rebuild sstables with correct bloom filters, with no data lost. (If your cluster was never on 0.7.0 or earlier, you don't have to worry about this.) Note that nodetool scrub will snapshot your data files before rebuilding, just in case. Solution: upgrade to 0.7.4, run scrub 2011/3/25 Kazuo YAGI<ky...@zynga.co.jp>:Hi everyone, I'm running 10 cassandra nodes in total and updated 5 nodes from 0.7.0 to 0.7.2 one by one like below. # sudo /etc/init.d/cassandra stop # sudo yum update cassandra-0.7.2-4 # sudo /etc/init.d/cassandra start After updating, those 5 updated nodes keep outputting error messages to /var/lib/cassandra/log/system.log every exactly 5 minutes.
