I noticed an issue in MapR 2.1.3. The directory name of hadoop in MapR dir is hadoop-0.20.2, but actually it's hadoop 1.0.3. 

* Will the directory name of hadoop change in future?
* Is it possible to add a symbol link to the real hadoop directory when the mapr package is installed ? (e.g. link /opt/mapr/hadoop/hadoop  to  /opt/mapr/hadoop/hadoop-0.20.2/ )
