Hi all,

I had built up a HDF 3.3.1.0 with ambari, but I got NoClassDefFoundError when I'm building a data processing kafka to druid by Streaming Analytics Manager, how to fix it?

My environment:

Storm:1.2.1
SAM: 0.6.0
Kafka: 1.0.0.3.1
Druid: 0.12.1

Below is the logs in storm worker.

Hi all,
I had resolved this problem by add missing jar files to "/usr/hdp/3.1.0.0-78/storm/lib/" .

Thanks.
