--------------------------------------

             Summary: allow moving and symlinking binaries
                 Key: SPARK-8760
                 URL: https://issues.apache.org/jira/browse/SPARK-8760
             Project: Spark
          Issue Type: Improvement
          Components: PySpark, Spark Shell, Spark Submit, SparkR
    Affects Versions: 1.4.0
            Reporter: Philipp Angerer
            Priority: Minor


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}
