partition by issue

[Jakub Wszolek]

I have a problem with adding partitions to the following HQL code.
Query below works fine, but when I try to add PARTITION BY (look second query) it dies with Null pointer exception.

CREATE EXTERNAL TABLE ingestion_csv_test
(
one string,
two string
)
ROW FORMAT SERDE 'com.bizo.hive.serde.csv.CSVSerde'
with serdeproperties (
"separatorChar" = "|"
)
LOCATION '/user/cloudera/hive-csv';

Problematic query below:

CREATE EXTERNAL TABLE ingestion_csv_test
(
one string,
two string
)
PARTITIONED BY (ingestion_dt STRING)
ROW FORMAT SERDE 'com.bizo.hive.serde.csv.CSVSerde'
with serdeproperties (
"separatorChar" = "|"
)

Exception:

hive> alter table ingestion_csv_test add partition (ingestion_dt = '2016-01-01') location '/user/cloudera/hive-csv';
OK
Time taken: 0.093 seconds

hive> select * from ingestion_csv_test;
