-----------------------------------------------------------------
This happens only when querying for some particular values on a secondary index. Cannot reproduce it querying by primary key.
Neither of the following did any good:
{noformat}
Restarting Cassandra
nodetool rebuild_index DB TABLE INDEX
nodetool invalidaterowcache
nodetool invalidatekeycache
nodetool cleanup
nodetool repair
{noformat}
