Cheng Lian commented on SPARK-7763:
-----------------------------------
This bug also disables metastore relation cache for partitioned tables, because
loaded tables lost partition information.
> Partition columns of data source tables should be persisted into metastore
> when creating persisted tables

> Key: SPARK-7763
> URL: https://issues.apache.org/jira/browse/SPARK-7763
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.4.0
> Reporter: Cheng Lian
> Assignee: Cheng Lian
> Priority: Blocker
>
> Partition columns of {{HadoopFsRelation}} should be persisted into Hive
> metastore together with relation schema. However, storing paths of all
> partitions into metastore might become a bottleneck. Instead, we always do a
> partition discovery while loading back the relation.
