partition by issue #29

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;
