Eric Yang commented on HADOOP-7563:
-----------------------------------
source jar is for remote debugging. It is important to keep running jar and
source jar in the same place to ensure the debugging session is showing the
right source code, and having test jar would help to validate the cluster like
teragen, and terasort. Hence, having them loaded to the class path are nice to
have.

> HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME was set to
> HADOOP_PREFIX/share/hadoop/hdfs and HADOOP_PREFIX/share/hadoop/mapreduce.
> This setup confuses the location of hdfs and mapred scripts. Instead the
> script should look for hdfs and mapred script in HADOOP_PREFIX/bin.
