> Repeated calls sbin/spark-config.sh file Causes ${PYTHONPATH} Value duplicate
> -----------------------------------------------------------------------------
>
> Key: SPARK-17336
> URL: https://issues.apache.org/jira/browse/SPARK-17336
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 2.0.0
> Reporter: anxu
>
> On Spark start up by command: sbin/start-all.sh, the sbin/spark-config.sh
> Repeated calls. In sbin/spark-config.sh code.
> {code:title=sbin/spark-config.sh|borderStyle=solid}
> # Add the PySpark classes to the PYTHONPATH:
> export PYTHONPATH="${SPARK_HOME}/python:${PYTHONPATH}"
> export PYTHONPATH="${SPARK_HOME}/python/lib/py4j-0.10.3-src.zip:${PYTHONPATH}"
> {code}
> {color:red}PYTHONPATH{color} has duplicate Value.
> example:
> {code:borderStyle=solid}
