------------------------------------
Resolution: Not A Problem
Please open new jira, still it is a problem on master.
> [Hive-Hbase Integration]:Data is not inserted into the hbase table from the
> hive table if the value is null even if the row key is not null
> -------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: HIVE-3336
> URL: https://issues.apache.org/jira/browse/HIVE-3336
> Project: Hive
> Issue Type: Bug
> Components: HBase Handler
> Affects Versions: 0.9.0
> Reporter: Kristam Subba Swathi
> Assignee: Chinna Rao Lalam
>
> Scenario
> ------------
> 1.create a new HBase table which is to be managed by Hive, use the STORED BY
> clause on CREATE TABLE as follows
> Query:
> {noformat}
> CREATE TABLE hbase_table_join(key int, value string)
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:val")
> TBLPROPERTIES ("hbase.table.name" = "xyz_join");
> {noformat}
> 2.Create two tables in hive and load data into the table as follows
> table1:
> {noformat}
> describe hive_hbase_1;
> OK
> empno int
> ename string
> deptno int
> hive> select * from hive_hbase_1;
> OK
> 1 a 1
> 2 q 10
> 3 w 12
> 4 w 12
> 4 w 12
> 5 r 13
> {noformat}
> table2:
> {noformat}
> hive> describe hive_hbase_2;
> OK
> deptno int
> dname string
> count int
> Time taken: 0.214 seconds
> hive> select * from hive_hbase_2;
> OK
> 11 a 11
> 12 q 101
> 13 w 121
> 14 w 121
> 2 we13 NULL
> 4 w 12
> 5 r 13
> {noformat}
> 3.Insert the join result of these tables into hbase_table_join as follows
> {noformat}
> hive> insert into table hbase_table_join select /*+mapjoin(hive_hbase_1)*/
> hive_hbase_2.deptno,hive_hbase_1.ename from hive_hbase_1 right outer join
> hive_hbase_2 on hive_hbase_1.deptno=hive_hbase_2.deptno;
> {noformat}
> Actual result of the select query is
> ---------------
> {noformat}
> 11 NULL
> 12 w
> 12 w
> 12 w
> 13 r
> 14 NULL
> 2 NULL
> 4 NULL
> 5 NULL
> {noformat}
> But the above insert query is failing because of the following exception
> ---------------------
> {noformat}
