Michael Allman updated SPARK-15968:
-----------------------------------
Description: 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. (was: 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 partitioned tables. As a result, cache lookups on partitioned
tables always miss and these relations are always recomputed.)
> HiveMetastoreCatalog does not correctly validate partitioned metastore
> relation when searching the internal table cache
