Jesus Camacho Rodriguez commented on HIVE-21072:
------------------------------------------------
[~b.maidics], have you verified whether HIVE-20707 fixes the issue ([~viirya]'s
patch seems to be a part of it)? AFAIK it could be backported if needed, there
is a branch-3 patch in the JIRA but apparently it was pushed.

> Key: HIVE-21072
> URL: https://issues.apache.org/jira/browse/HIVE-21072
> Project: Hive
> Issue Type: Bug
> Reporter: Liang-Chi Hsieh
> Priority: Major
> Labels: pull-request-available

> 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}
