> Is there way to make cassandra throw away the offending column? Running scrub should allow to get read of the row containing the problematic column. Unfortunately it will discard the whole row, not just the column. However, since scrub takes a snapshot anyway (and should tell you which sstable had the offending column), you could do that and keep the bad sstable around to further investigate.
