10110346 opened a new pull request #24446: [SPARK-27552][SQL]The configuration `hive.exec.stagingdir` is invalid on Windows OS URL: https://github.com/apache/spark/pull/24446 ## What changes were proposed in this pull requesst? If we set `hive.exec.stagingdir=.test-staging\tmp`, But the staging directory is still `.hive-staging` on Windows OS. Reasons for failure: Test code: ``` val path = new Path("C:\\test\\hivetable") println("path.toString: " + path.toString) println("path.toUri.getPath: " + path.toUri.getPath) ``` Output: ``` path.toString: C:/test/hivetable path.toUri.getPath: /C:/test/hivetable ``` We can see that `path.toUri.getPath` has one more separator than `path.toString`, and the separator is ' / ', not ' \ ' So `stagingPathName.stripPrefix(inputPathName).stripPrefix(File.separator).startsWith(".")` will return false ## How was this patch tested? Existed tests
