[jira] [Updated] (SPARK-31142) Remove useless conf set in pyspark
context
[ https://issues.apache.org/jira/browse/SPARK-31142?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dongjoon Hyun updated SPARK-31142:
----------------------------------
Affects Version/s: (was: 3.0.0)
> Remove useless conf set in pyspark context
> ------------------------------------------
>
> Key: SPARK-31142
> URL: https://issues.apache.org/jira/browse/SPARK-31142
> Project: Spark
> Issue Type: Improvement
> Components: PySpark, Spark Core
> Affects Versions: 3.1.0
> Reporter: Jackey Lee
> Priority: Major
>
> In Pyspark/context.py, we extract the configuration of the "spark.executorEnv" prefix from conf and put it in env. But in PythonWorkerFactory, we have already obtained these environment variables from ProgressBuilder, thus we do not need the extra copy.
> In addition, in some special environment deployments, user-configured environment variables such as "spark.executorEnv.Path=/usr/lib:$PATH" will be automatically parsed as actual machine confs. If we still directly copy and overwrite it, the configuration will be a wrong config.
