Subject Problem configuring Ganglia(jmxtrans) with Accumulo 1.7.0
Date Wed, 27 Jan 2016 12:22:22 GMT
I am trying to setup Ganglia for Monitoring Accumulo 1.7.0 Cluster 
having 5 nodes. I also configured ganglia for Accumulo 1.6.1 standalone 
cluster which is working fine and shows all the required metrices 
related to Accumulo.

After scanning jmxtrans.log, I found that the its not exexuting quring 
properly. It starts the job and finish in next line

cronExpression=null, numQueryThreads=null]

But this not the case with Accumulo 1.6.1 cluster it executes the query 
and send the ganglia metrices which I can see on ganglia web ui...

At the ganglia Web UI, I can not see any Accumulo metrices for this 
cluster.I have checked every configurations hundreds of times.
If anyone want, I can upload configurations, procedure or any required 
info. Please comment on what could be the problem in query execution? 
and how can I fix it?
Is it a compatibility issue with Accumulo 1.7.0?

Thanks
