             Summary: Hive throws NPE when writing struct and list types data to a HBase backed table
                 Key: HIVE-18969
                 URL: https://issues.apache.org/jira/browse/HIVE-18969
             Project: Hive
          Issue Type: Bug
            Reporter: Kryvenko Igor
            Assignee: Kryvenko Igor


"INSERT INTO" query fails with NPE when we inserting STRUCT datatype with null values into a table stored in Hbase. The same issue for MAP datatype is already resolved in https://issues.apache.org/jira/browse/HIVE-13065

*Steps to reproduce*
*1. Create tables:*

{code}
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');

{code}
*2. Insert into table stored the struct with NULL value in it:*
{code}
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;
{code}

The mapreduce job for insert query fails. Error messages are as below:
