sandeep katta 7e6142591f [SPARK-28840][SQL] conf.getClassLoader in SparkSQLCLIDriver should be avoided as it returns the UDFClassLoader which is created by Hive ... ### What changes were proposed in this pull request? Spark loads the jars to custom class loader which is returned by `getSubmitClassLoader` . [Spark code](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L337) **In 1.2.1.spark2 version of Hive** `HiveConf.getClassLoader` returns same the class loader which is set by the spark **In Hive 2.3.5** `HiveConf.getClassLoader` returns the UDFClassLoader which is created by Hive. Because of this spark cannot find the jars as class loader got changed [Hive code](https://github.com/apache/hive/blob/rel/release-2.3.5/ql/src/java/org/apache/hadoop/hive/ql/session/SessionState.java#L395) ### Why are the changes needed? Before creating `CliSessionState` object save the current class loader object in some reference. After SessionState.start() reset back class Loader to the one which saved earlier. ### Does this PR introduce any user-facing change? No ### How was this patch tested? Added Test case and also Manually tested **Before Fix**  **After Fix**  Closes #25542 from sandeep-katta/jarIssue.
