>                 Key: SPARK-25404
>                 URL: https://issues.apache.org/jira/browse/SPARK-25404
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 2.3.1
>            Reporter: Jinhua Fu
>            Priority: Minor
>
> Considering the follow scenario:
>  
> {code:java}
> SET hive.exec.stagingdir=temp;
> CREATE TABLE tempTableA(key int)  location '/spark/temp/tempTableA';
> INSERT OVERWRITE TABLE tempTableA SELECT 1;
> {code}
> We expect the staging path under the table path, such as '/spark/temp/tempTableA/.hive-stagingXXX'(SPARK-20594), but actually it is '/spark/tempXXX'.
> I'm not quite sure why we use the 'if ... else ...' when getting a stagingDir, but it maybe the cause of this bug.
>  
> {code:java}
> // SaveAsHiveFile.scala
> private def getStagingDir(
>     inputPath: Path,
>     hadoopConf: Configuration,
>     stagingDir: String): Path = {
>   ......
>   var stagingPathName: String =
>   if (inputPathName.indexOf(stagingDir) == -1) {
>     new Path(inputPathName, stagingDir).toString
>   } else {
>     // The 'indexOf' may not get expected position, and this may be the cause of this bug.
>     inputPathName.substring(0, inputPathName.indexOf(stagingDir) + stagingDir.length)
>   }
>   ......
> }
> {code}
