----------------------------------------
I've created a revised PR for this issue,
https://github.com/apache/spark/pull/13818.
> HiveMetastoreCatalog does not correctly validate partitioned metastore
> relation when searching the internal table cache
> -----------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-15968
> URL: https://issues.apache.org/jira/browse/SPARK-15968
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Michael Allman
> Labels: hive, metastore
>
> The {{getCached}} method of {{HiveMetastoreCatalog}} computes
> {{pathsInMetastore}} from the metastore relation's catalog table. This only
> returns the table base path, which is not correct for non-empty partitioned
> tables. As a result, cache lookups on non-empty partitioned tables always
> miss and these relations are always recomputed.
