Subject Re: Hadoop configuration defaults

Hi Marco,

You can add hadoop properties in your whirr properties file like this:

hadoop-mapreduce.mapred.child.java.opts=-Xmx1000m
hadoop-mapreduce.mapred.child.ulimit=1500000

See http://www.searchworkings.org/blog/-/blogs/running-mahout-in-the-cloud-using-apache-whirr

Cheers,

Frank
