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
