holdenk closed SPARK-8760.
--------------------------
Resolution: Fixed
This is a "partially fixed" but I think fixed is a close enough description. We
don't use readlink but we do check for the current SPARK_HOME before running
and if the user has a custom SPARK_HOME then can just point it there since we
no longer overwrite it in `spark-submit`.
> allow moving and symlinking binaries

> you use the following line to determine {{$SPARK_HOME}} in all binaries
> {code:none}
> export SPARK_HOME="$(cd "`dirname "$0"`"/..; pwd)"
> {code}
> however users should be able to override this. also symlinks should be
> followed:
> {code:none}
> if [[ -z "$SPARK_HOME" ]]; then
> export SPARK_HOME="$(dirname "$(readlink -f "$0")")"
> fi
> {code}
