--------------------------------------
This may not be related to the UPDATE.
I dropped and recreated the CF and still had the same issue.
{code}
[default@cathy] drop column family users;

Waiting for schema agreement...
... schemas agree across the cluster
[default@cathy] create column family users with comparator = UTF8Type and
key_validation_class=UTF8Type and column_metadata = [{column_name: password,
validation_class: UTF8Type}];

> Reporter: Cathy Daw
> Priority: Critical
>
> *Reproduction Steps*
> {code}
