[jira] [Closed] (SPARK-8760) allow moving and symlinking binaries

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`.

> {code:none}
> export SPARK_HOME="$(cd "`dirname "$0"`"/..; pwd)"
> {code}
> however users should be able to override this. also symlinks should be followed:
