All,
  I am getting an error using the CassandraCounterBatchingBolt complaining of 
an ….

invalid operation for non commutative column family LogVolumeByMinute

 I am following a tutorial from a book which is using Casandra to store text in 
a Column Family and auto-increment a counter column. I read that in order to 
use a counter column I had to have a default_validation_class of type 
CounterColumnType. So I created a CF like so

create column family LogVolumeByMinute with 
default_validation_class=CounterColumnType and key_validation_class=UTF8Type 
and comparator=UTF8Type;



  But when I did this and triggered some logs to my syslog, which in turn 
triggered the cassandra insertion, the CF got somehow destroyed such that I 
couldn't even view the contents. But I don’t get any errors in the worker logs 
at all. Has anyone had any experience with CassandraCounterBatchingBolt and if 
so would you mind giving me your thoughts/insight.

Thanks all.
