HI,
We are working with kerberos CDH 5.7.3 & CM 5.8.
I create a Hive Table on HBase with the below command:
create external table arch_mr_jobs
(job_id STRING,
dt STRING,
a STRING,
b STRING,
.......
)STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
("hbase.columns.mapping"=":key,d:dt,d:a,d:b,......) TBLPROPERTIES("hbase.table.name"="arch:mr_jobs);
There is just one row that has the column d:a in hbase table arch:mr_jobs. There are no d:a column in other rows. So， the strange behavior comming:
select a,count(1) from arch_mr_jobs; got:
FAILED | 1
--You can see: There is just one row ,I hope the result should be:
FAILED | 1
NULL | 50
--why the null value be ignore? This is a wrong result.
select a from arch_mr_jobs; got:
FAILED |
--I hope the result should be:
FAILED
NULL
NULL
.
.
So, I believe I missed some config. I google but got nothing.
Could you give me any point?
Thank you at advance
Paul
