> HIVE-20241 adds support of partitioned CTAS statements:
> {code:sql}
> CREATE TABLE partition_ctas_1 PARTITIONED BY (key) AS
> SELECT value, key FROM src where key > 200 and key < 300;{code}
>
> However, I've tried this feature by checking out latest branch-3, and encountered NPE:
> {code:java}
> hive> CREATE TABLE t PARTITIONED BY (part) AS SELECT 1 as id, "a" as part;
> FAILED: NullPointerException null
> {code}
> I also ran the query test partition_ctas.q. The test passes when using TestMiniLlapLocalCliDriver, but when I go to test it with TestCliDriver manually, it also throws NullPointerException:
> {code:java}
