Subject Re: Spark Performance on Yarn
Date Fri, 20 Feb 2015 17:40:45 GMT
A bit more context on this issue. From the container logs on the executor 

Given my cluster specs above what would be appropriate parameters to pass
into :
--num-executors --num-cores --executor-memory 

I had tried it with --executor-memory 2500MB
