How do I add a custom comparator class to a cassandra cluster ?
I need to add a custom comparator to a cluster, to sort columns in a certain customized fashion. How do I add the class to the cluster ?

Disclaimer: I've never tried, but I'd imagine you can drop a JAR containing the class(es) into the lib directory and perform a rolling restart of the nodes.

Re: How do I add a custom comparator class to a cassandra cluster ?
That's right. Create class that implements the required interface and then drop that jar in lib directory and start the cluster.

Re: How do I add a custom comparator class to a cassandra cluster ?
Can I put this comparator class in a separate new jar(with just this single file) or is it to be appended to the original jar along with the other comparator classes?

it can be in a separate jar with just one class.

How do I add the class to the cluster ? I highly recommend against doing this, because you'll be locked in to your comparator and not have an easy way out. I dare say if none of the currently available comparators meet your needs, you're doing something wrong. -Brandon

@Brandon : I just created a jira issue to request this type of comparator along with Cassandra. It is about a UTF8 comparator that provides case insensitive ordering of columns.
