Jinhua Fu created SPARK-25404:
---------------------------------
Summary: 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
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}
private def getStagingDir(
inputPath: Path,
hadoopConf: Configuration,
stagingDir: String): Path = {
......
var stagingPathName: String =
if (inputPathName.indexOf(stagingDir) == -1) {
new Path(inputPathName, stagingDir).toString
} else {
inputPathName.substring(0, inputPathName.indexOf(stagingDir) +
stagingDir.length)
}
......
}
{code}
