Could not resolve type id 'c*' into a subtype of [simple type, class io.druid.segment.loading.LoadSp

Hi all,

I am using druid 0.8.1 with Cassandra as a deep storage. In historical node i am getting the following error repeatedly.

Which version of Cassandra? This module is community maintained and not supported by the committers. I don’t believe it works with Cassandra 2.x

Hey Roshni,

Could you double-check that the cassandra extension is actually getting loaded on the historical node? That error makes it look like it’s not.

One way to confirm is to visit http://HISTORICAL_IP:PORT/status and check that is in the list of modules.

Thanks guys,Its working now for me.We updated druid-cassandra-storage and it started working for me.
