[jira] [Commented] (SPARK-15968) HiveMetastoreCatalog does not correctly validate partitioned metastore relation when searching the internal table cache

    [ https://issues.apache.org/jira/browse/SPARK-15968?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15332074#comment-15332074 ]

----------------------------------------

I have a patched based on the way this method was implemented in Spark 1.5. I'm working on a PR presently.

> 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.
