Subject Re: What configuration parameters cause a Hadoop 2.x job to run on the cluster
Date Fri, 25 Apr 2014 16:00:03 GMT
What version of Hadoop you are using? (YARN or no YARN)
To answer your question; Yes its possible and simple. All you need to to is
to have Hadoop JARs on the classpath with relevant configuration files on
the same  classpath pointing to the Hadoop cluster. Most often people
simply copy core-site.xml, yarn-site.xml etc from the actual cluster to the
application classpath and then you can run it straight from IDE.

Not a windows user so not sure about that second part of the question.
