Description

STR (Structure)

STEP 1. Create tables

CREATE TABLE IF NOT EXISTS t1 (id INT);
INSERT INTO TABLE t1 VALUES (1),(2),(3),(4),(5);
CREATE TABLE IF NOT EXISTS `htable`(
  `id` INT, 
  `map_column` STRUCT<s_int:INT,s_string:STRING,s_date:DATE>) ROW FORMAT SERDE 'org.apache.hadoop.hive.hbase.HBaseSerDe'  STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'  WITH SERDEPROPERTIES (   'hbase.columns.mapping'=':key,id:id',    'serialization.format'='1') TBLPROPERTIES ( 'hbase.table.name'='tmp/h');

STEP 2. Insert into table stored in HBase the struct with NULL value in it

INSERT INTO `htable` SELECT 2,NAMED_STRUCT("s_int",CAST(NULL AS INT),"s_string","s1","s_date",CAST('2018-03-12' AS DATE)) FROM t1 LIMIT 1;

ACTUAL RESULT

The query fails with NPE.

EXPECTED RESULT

STR (arrays)

STEP 1. Create tables

CREATE TABLE hbase_list(id INT, list_column array<string>) ROW FORMAT SERDE 'org.apache.hadoop.hive.hbase.HBaseSerDe' STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ('hbase.columns.mapping'=':key,id:id', 'serialization.format'='1') TBLPROPERTIES ( 'hbase.table.name'='tmp/htest');

STEP 2. Insert into table stored in HBase the array with NULL value in it

insert into hbase_list SELECT 2, array("a", CAST (NULL AS STRING),  "b") FROM t1 LIMIT 1;

ACTUAL RESULT

The query fails with NPE.
