-----------------------------
Issue Type: Improvement (was: Bug)
> partition path created by Hive should be deleted after rename a partition
> with upper-case
> -----------------------------------------------------------------------------------------
>
> Key: SPARK-19359
> URL: https://issues.apache.org/jira/browse/SPARK-19359
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Song Jun
> Priority: Minor
>
> Hive metastore is not case preserving and keep partition columns with lower
> case names.
> If SparkSQL create a table with upper-case partion name use
> HiveExternalCatalog, when we rename partition, it first call the HiveClient
> to renamePartition, which will create a new lower case partition path, then
> SparkSql rename the lower case path to the upper-case.
> while if the renamed partition contains more than one depth partition ,e.g.
> A=1/B=2, hive renamePartition change to a=1/b=2, then SparkSql rename it to
> A=1/B=2, but the a=1 still exists in the filesystem, we should also delete it.
