[geowave-dev] Newbie: Unable to run on YARN with Log4J error? (CDH)
Hi folks,

I am new to geowave and trying to following the vector walkthrough [1].
I'm familiar with HBase, YARN etc. and I'm running on a local CDH 5.12 cluster and I have 2 populated tables in HBase so some data.

When I try and run the step of the "geowave analytic kde..." [2] it submits an MR job to YARN which fails.  YARN is logging a Log4J stack track for the task attempt which I've put below.

Exception in thread "main" java.lang.ExceptionInInitializerError

This is obviously something config related but does anyone have any idea where to start debugging this please?  

Thank you to anyone who can help.

Best wishes,
Tim
