------------------------------------
> 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
> Priority: Major
>
> "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:
> {code}
