#1 wmr-config.sh misdetects HADOOP_HOME w/ Cloudera Hadoop

[Tim Yates]

The wmr-conf.sh script in the backend does not automatically detect the correct HADOOP_HOME when Cloudera Hadoop is installed. It finds /usr/bin/hadoop-0.20 on the path and then assumes that /usr/bin is the correct HADOOP_HOME (it should be /usr/lib/hadoop-0.20). Since /usr/bin/hadoop-0.20 is a real (dummy) script and not a link, there is no easy way to fix this. HADOOP_HOME should be more directly configurable to avoid this problem.
