Craig Macdonald commented on HADOOP-3763:
-----------------------------------------

In similar lines, I would like to be able to directly call the script from 
autofs. If I point autofs to the wrapper script in the currently installed 
Hadoop version, can the wrapper script determine automatically the location of 
HADOOP_HOME? Perhaps it can even import conf/hadoop-env.sh?

> Make fuse_dfs_wrapper.sh add the fuse_dfs executable in the hadoop deployment 
> directory to its path

> This will make it easier to do upgrades and debug configuration problems
