yunliangchen created HBASE-17687:
------------------------------------

             Summary: hive on hbase table and phoenix table can't  be selected
                 Key: HBASE-17687
                 URL: https://issues.apache.org/jira/browse/HBASE-17687
             Project: HBase
          Issue Type: Improvement
          Components: hbase
    Affects Versions: 1.0.2
         Environment: hadoop 2.7.2
hbase 1.0.2
phoenix 4.4
hive 1.3
all above are based on huawei FusionInsight HD(FusionInsight V100R002C60U10SPC001)
            Reporter: yunliangchen


First , I created a table on phoenix, as this:
---------------------------------------------------------------------------
DROP TABLE IF EXISTS bidwd_test01 CASCADE;
CREATE TABLE IF NOT EXISTS bidwd_test01(
   rk VARCHAR,
   c1 integer,
   c2 VARCHAR,
   c3 VARCHAR,
   c4 VARCHAR
   constraint bidwd_test01_pk primary key(rk)
)
COMPRESSION='SNAPPY'
;
---------------------------------------------------------------------------
And then , I upserted two rows into the table:
---------------------------------------------------------------------------
upsert into bidwd_test01 values('001',1,'zhangsan','20170217','2017-02-17 12:34:22');
upsert into bidwd_test01 values('002',2,'lisi','20170216','2017-02-16 12:34:22');
---------------------------------------------------------------------------
At last , I scaned the table like this:
---------------------------------------------------------------------------
select * from bidwd_test01;
---------------------------------------------------------------------------

It's OK by now, but, I want to create a hive on hbase table ,that mapping to the phoenix table
, the script likes this:
---------------------------------------------------------------------------
USE BIDWD;
DROP TABLE test01;
CREATE EXTERNAL TABLE test01
(
 rk string,
 id int,
 name string,
 datekey string,
 time_stamp string
)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'  
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,0:C1,0:C2,0:C3,0:C4")  
TBLPROPERTIES ("hbase.table.name" = "BIDWD_TEST01");
---------------------------------------------------------------------------

So,I also try to insert some data into the table,and scan this table:
---------------------------------------------------------------------------
set hive.execution.engine=mr;
insert into test01 values('003',3,'lisi2','20170215','2017-02-15 12:34:22');
select * from test01;
---------------------------------------------------------------------------

But,there are some problems like this:
+------------+------------+--------------+-----------------+----------------------+--+
| test01.rk  | test01.id  | test01.name  | test01.datekey  |  test01.time_stamp   |
+------------+------------+--------------+-----------------+----------------------+--+
| 001        | NULL       | zhangsan     | 20170217        | 2017-02-17 12:34:22  |
| 002        | NULL       | lisi         | 20170216        | 2017-02-16 12:34:22  |
| 003        | 3          | lisi2        | 20170215        | 2017-02-15 12:34:22  |
+------------+------------+--------------+-----------------+----------------------+--+

the column "id" 's value was null,only the last row is ok.
but,when I scan data in the phoenix ,there are some errors like this:
Error: ERROR 201 (22000): Illegal data. Expected length of at least 115 bytes, but had 31
(state=22000,code=201)
java.sql.SQLException: ERROR 201 (22000): Illegal data. Expected length of at least 115 bytes,
but had 31

	at sqlline.SqlLine.start(SqlLine.java:292)
	at sqlline.SqlLine.main(SqlLine.java:194)

So,I don't know why? How can I solve this problem?
