> We experienced a case that sometimes we accidentally started HDFS or 
> MAPREDUCE with root user. Then the directory permission will be modified and 
> we have to chown them. It will be nice if there can be a username checking in 
> the hadoop-daemon.sh script so that we always start with the desired username.
