Mahout clustering test failing on connectivity full test

I am running RapidMiner Studio 7.2 and connecting to a stock Cloudera QuickStart 5.7 VM with 4 CPUs and 24GB of RAM. When I run the connectivity full test, it fails on the Mahout clustering job. It looks like the error involves a java heap allocation, but I am not sure which one I should change. I have attached the test logs and added the map reduce log into the zip file. Does anyone have any idea what is going on?

 

Thanks!

    Hi,

    the Mahout jobs usually need more memory for the Map tasks as the Quickstart VM's default configuration. Try to set 

    mapreduce.map.java.opts=-Xmx256m

    as an Advanced Hadoop parameter.

    Thanks! That also fixed the Pig script test, which was also failing. I am completing the entire test now.
