             Summary: Introduce a global config system to replace hadoopConfiguration
                 Key: SPARK-27520
                 URL: https://issues.apache.org/jira/browse/SPARK-27520
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.0.0
            Reporter: Xingbo Jiang


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.
