Description

On Spark start up by command: sbin/start-all.sh, the sbin/spark-config.sh Repeated calls. In sbin/spark-config.sh code.

sbin/spark-config.sh

# 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}"

PYTHONPATH has duplicate Value.
example:

axu4iMac:spark-2.0.0-hadoop2.4 axu$ sbin/start-all.sh  | grep PYTHONPATH
axu.print [Log] [6,16,31] [sbin/spark-config.sh] 定义PYTHONPATH
axu.print [sbin/spark-config.sh] [Define Global] PYTHONPATH(1): [/Users/axu/code/axuProject/spark-2.0.0-hadoop2.4/python:]
axu.print [Log] [7,17,32] [sbin/spark-config.sh] 再次定义PYTHONPATH
axu.print [sbin/spark-config.sh] [Define Global] PYTHONPATH(2): [/Users/axu/code/axuProject/spark-2.0.0-hadoop2.4/python/lib/py4j-0.10.1-src.zip:/Users/axu/code/axuProject/spark-2.0.0-hadoop2.4/python:]
