Thanks Aaron,
I created a script and everything went OK. I think that the problem is
when you try to update a CF. Below, I try to change the column
comparator and it complains that the 'comparators do not match'. Can
you enlighten me on what that means? There is no data in the CF at this
point.
[default@Keyspace1] create column family User3;
503dba20-924b-11e0-0000-f1169bb35ddf
Waiting for schema agreement...
... schemas agree across the cluster
[default@Keyspace1] set User3['1']['name'] = 'mike';

What does "comparators do not match" mean?
Thanks,

Can you provide the cli script to create the schema and info on how many nodes
you have.

Granted, there are no rows in the CF yet (see probs below), but this exception
seems to be during the parsing stage.
I've check everything else, AFAIK, so I'm at a loss.
Much obliged.
