Apache Spark reassigned SPARK-25404:
------------------------------------
Assignee: Apache Spark
> Staging path may not on the expected place when table path contains the
> stagingDir string
> -----------------------------------------------------------------------------------------
>
> 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
> Assignee: Apache Spark
> 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}
