Not sure about Cassandra.. but DB connection objects typically are not thread
safe... ie you cannot have to two threads issue queries/write over the same
connection at the same time.

Hi all,
Just wanted to give an update (in case anyone is interested), since the issue
has been solved now. Turns out maven shade plugin was configured incorrectly.
We were excluding classes based on mask instead of using recommended provided
scope for storm dependency. Switching to maven shade configuration provided as
example in storm docs has helped.
