[jira] [Commented] (SPARK-27520) Introduce a global config system
to replace hadoopConfiguration

Thomas Graves commented on SPARK-27520:
---------------------------------------
Can we add more to the description to explain why we are doing this? I'm assuming this is to allow users to more easily change it.

> hadoopConf can be accessed via `SparkContext.hadoopConfiguration` from both user code and Spark internal. The configuration is mainly used to read files from hadoop-supported file system(eg. get URI/get FileSystem/add security credentials/get metastore connect url/etc.)
> We shall keep a global config that users can set and use that to track the hadoop configurations, and avoid using `SparkContext.hadoopConfiguration`, maybe we shall mark it as deprecate.
