/usr/lib/hadoop is the default HADOOP_HOME in CDH4.

Regarding deprecation, it appears HADOOP_PREFIX is the replacement for HADOOP_HOME:

$HADOOP_HOME is deprecated

I believe HADOOP_MAPRED_HOME is only used for the map reduce infrastructure, if you are using HDFS directly, then you probably want HADOOP_PREFIX.

Try to echo : HADOOP_MAPRED_HOME .
AFAIK, HADOOP_HOME is deprecated and HADOOP_MAPRED_HOME is the new one for MapReduce1 and MapReduce2.
