Hi, @gatorsmile . I investigated the related PRs.
* #12934 `[SPARK-14127][SQL] Makes 'DESC [EXTENDED|FORMATTED] <table>'
support data source tables`
* #12844 `[SPARK-14127][SQL] Native "DESC [EXTENDED | FORMATTED] <table>"
DDL command`
* #13025 `[SPARK-14127][SQL] "DESC <table>": Extracts schema information
from table properties for data source tables`
Unfortunately, those are extracting the partition column **names** from
table properties. But, table properties does not have partition column
**values**. Currently, Spark does not hold the partitioned column values of
`Datasource` table in `CatalogTable`.
In this case, I'd like to make another issue for that since that's really a
new feature. Since it's not supported Spark 1.6, I think it's nice-to-have
item, not a must-to-have item in this PR. How do you think about that?
