Major Description
Currently, TestHadoopSmoke fails because it looks by default in /usr/lib/hadoop/contrib/streaming for the Hadoop streaming jar. The streaming jar has moved to /usr/lib/hadoop-mapreduce.
I edited TestHadoopExamples to look for the examples jar in HADOOP_MAPRED_HOME. Currently, it wants the user to specify HADOOP_HOME, but this is usually /usr/lib/hadoop, and in the Bigtop packages the examples jar has moved to /usr/lib/hadoop-mapreduce.
