Subject Re: Error messages after rolling updating cassandra from 0.7.0 to 0.7.2
Date Fri, 25 Mar 2011 13:39:43 GMT
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
