-For Apache Hadoop versions 1.x, Cloudera CDH "mr1" distributions, and other Hadoop versions without YARN, use:
-
-{% highlight bash %}
-# Apache Hadoop 1.2.1
-mvn -Dhadoop.version=1.2.1 -Phadoop-1 -DskipTests clean package

-# Cloudera CDH 4.2.0 with MapReduce v1
-mvn -Dhadoop.version=2.0.0-mr1-cdh4.2.0 -Phadoop-1 -DskipTests clean package

You can enable the `yarn` profile and optionally set the `yarn.version` property if it is different from `hadoop.version`. Spark only supports YARN versions 2.2.0 and later.
