Liang-Chi Hsieh created HIVE-21072:
--------------------------------------
Summary: NPE when runnign partitioned CTAS statements
Key: HIVE-21072
URL: https://issues.apache.org/jira/browse/HIVE-21072
Project: Hive
Issue Type: Bug
Reporter: Liang-Chi Hsieh
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}
