This code is introduced form #12770, do you check the relative UT? Maybe UT relating with SessionState and DDLSuite.

Yes, I had checked the pr #12770 too. But I'm not very clear why we should do like that.

if (inputPathName.indexOf(stagingDir) == -1) {
new Path(inputPathName, stagingDir).toString
} else {
inputPathName.substring(0, inputPathName.indexOf(stagingDir) + stagingDir.length)
}
var stagingPathName: String = new Path(inputPathName, stagingDir).toString

// SPARK-20594: This is a walk-around fix to resolve a Hive bug. Hive requires that the
// staging directory needs to avoid being deleted when users set hive.exec.stagingdir
