Hi @srowen , yes the actual problem is to find to out where Spark is
installed through symlink.
Yes, sourcing can follow the symlink, but the problem is how to find the
path of sourcing file/symlink.
Say if we make `spark-shell` as a symlink and add to /usr/bin, when we
execute this `spark-shell` in any directory, how to identify the path of
sourcing file? If sourcing file is not linked to `/usr/bin/xx`, we still need
to find out where Spark is installed.
