Subject Re: How to set Spark executor memory?
Date Sat, 21 Mar 2015 15:48:51 GMT
If you are running from your IDE, then I don't know what you are
running or in what mode. The discussion here concerns using standard
mechanisms like spark-submit to configure executor memory. Please try
these first instead of trying to directly invoke Spark, which will
require more understanding of how the props are set.
