Hi Manu,

Glad that you have the issue resolved.

If i understand the issue correctly....
Your cassandra installation had RandomParitioner but the bulk loader
configuration (cassandra.yaml) had Murmur3Partitioner?
By fixing the cassandra.yaml for the bulk loader the issue got resolved?

If not then we might have a bug and your feedback might help the community.

Regards,
</VJ>
