Subject Re: [Question] Stopping Storm, Metron & Kafka doesn't stop all Storm processes?
Date Thu, 17 Aug 2017 20:35:16 GMT
That seems close to the issue that I'm having... But there's a part I 
don't quite understand in my case.

Everything's working fine for days and then suddenly, Java throws an 
error (see other mail to the mailing list) and I can't get Metron stable 
again. It's always either the indexingBolt or hdfsIndexingBolt. The 
error I see the most after this is "java.lang.OutOfMemoryError: GC 
overhead limit exceeded"...

It seems that somewhere there's a big pileup of messages which Metron 
suddenly can't process.

Any ideas on how to further troubleshoot this?
