Subject: Compiling a mapreduce job under the new Apache Hadoop YARN

In the old Hadoop mapreduce v1 framework (e.g. 1.0.3) the way to compile =
a job was using the already provided "hadoop-core-HADOOP_VERSION.jar" =
through the following command:

    javac -cp ".../hadoop-core-HADOOP_VERSION.jar" -d class_dir =
Example.java

In the newest releases for Hadoop mapreduce v2 YARN (e.g. 2.0.1-alpha or =
the cloudera 4.0) a similar core.jar is not provided, though, to be used =
during compilation. The closest i have managed to get is by using the =
"hadoop-common-2.0.1-alpha.jar" in the /share/hadoop/common dir but this =
still leaves a lot of compilation errors.

Is there some other specific way or using different jars for compiling a =
YARN job? Or maybe for some reason you need to build the source yourself =
in the new releases to get the core.jar? I have searched quite a lot but =
can't find a relevant answer.

Thank you very much!=
