Xiao Li created SPARK-23573:
-------------------------------
Summary: Ban the usage of SparkContext.hadoopConfiguration
Key: SPARK-23573
URL: https://issues.apache.org/jira/browse/SPARK-23573
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Xiao Li
SparkContext.hadoopConfiguration should not be used directly in SQL module.
Instead, one should always use sessionState.newHadoopConfiguration(), which
blends in configs set per session.
The idea is to add the linter rule to ban it.
- Restrict the linter rule to the components that use SQL. use the parameter
`scalastyleSources`?
- Exclude genuinely valid uses, like e.g. in SessionState (ok, that can be done
per case with scalastyle:off in the code.
