Kent Yao created SPARK-22640:
--------------------------------
Summary: Can not switch python exec in executor side
Key: SPARK-22640
URL: https://issues.apache.org/jira/browse/SPARK-22640
Project: Spark
Issue Type: Bug
Components: PySpark
Affects Versions: 2.2.0
Reporter: Kent Yao
{code:java}
PYSPARK_PYTHON=~/anaconda3/envs/py3/bin/python \
bin/spark-submit --master yarn --deploy-mode client \
--archives ~/anaconda3/envs/py3.zip \
--conf spark.yarn.appMasterEnv.PYSPARK_PYTHON=py3.zip/py3/bin/python \
--conf spark.executorEnv.PYSPARK_PYTHON=py3.zip/py3/bin/python \
/home/hadoop/data/apache-spark/spark-2.1.2-bin-hadoop2.7/examples/src/main/python/mllib/correlations_example.py
{code}
In the case above, I created a python environment, delivered it via
`--arichives`, then visited it on Executor Node via
`spark.executorEnv.PYSPARK_PYTHON`.
But Executor seemed to use `PYSPARK_PYTHON=~/anaconda3/envs/py3/bin/python`
instead of `spark.executorEnv.PYSPARK_PYTHON=py3.zip/py3/bin/python`
