Eric Liang updated SPARK-18661:

>                 Key: SPARK-18661
>                 URL: https://issues.apache.org/jira/browse/SPARK-18661
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 2.1.0
>            Reporter: Eric Liang
>            Priority: Blocker
>
> Even though in 2.1 creating a partitioned datasource table will not populate the partition data by default (until the user issues MSCK REPAIR TABLE), it seems we still scan the filesystem for no good reason.
> We should avoid doing this when the user specifies a schema.
