All,

So I think we've found the root cause of this issue,, so I figured I'd report 
back. It appears that storm itself was not properly configured, and thus it was 
trying to pull in ganglia to log for all topologies. Once we removed the 
-javaagent flag from all of the Javaopts configurations for Storm, we got past 
this issue. See the link below for more details on this particular problem. We 
used the answer from aditya in this thread to solve the issue.

Thanks everyone for your help and input on this!

Subject: Re: Metron Not Reading From Kafka?

That's a pretty out dated version, and sounds like you may have an old version 
of HDP if you have the jmx error.

Also worth turning up the logging in storm for the parser topologies for a bit 
(via storm ui) on org.apache.metron.

All,

We have a Metron 0.4.3 installation on an HDP cluster which has a sensor set up 
to read from a Kafka topic and write the data out to Elasticsearch. Data is 
being inserted into the Kafka topic, and we can read that through Kafka console 
consumer, but the system is not reporting any data coming through. The Storm 
spout says no data has been processed, and the index hasn't even been created 
in Elastic, despite running for nearly a month now.

We've searched the worker logs for Storm, and the only error that comes up is a 
(we think) unrelated error about not being able to find the jmxmetrics JAR 
file. Metron reports that the topic is found, and does not tell us that the 
topic is not emitting, so we suspect it sees the data in there.

Do you all have any ideas on where we can look to determine the cause of this 
issue, or things to try?

Thanks!
