>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 2.2.0

> Sql below will get all partitions from metastore, which put much burden on metastore;
> {{CREATE TABLE test (value INT) PARTITIONED BY (dt STRING)}}
> {{SELECT * from test where dt=2017}}
> The reason is that the the analyzed attribute {{dt}} is wrapped in {{Cast}} and {{HiveShim}}
fails to generate a proper partition filter.
> Could we fix this? Sql like {{SELECT * from test where dt=2017}} is common in my warehouse.
