我正在尝试在hbase表上创建配置单元表。详情如下:
hbase表包含如下数据:
Connected to: Phoenix (version 4.7)
Driver: PhoenixEmbeddedDriver (version 4.7)
Autocommit status: true
Transaction isolation: TRANSACTION_READ_COMMITTED
Building list of tables and columns for tab-completion (set fastconnect to true to skip)...
1341/1341 (100%) Done
Done
sqlline version 1.1.8
0: jdbc:phoenix:maxiqtesting1.lti.com:2181:/h>
select * from HBASE_TEST_6JULY_1792409;
+---------+---------+---------+
| FIELD0 | FIELD1 | FIELD2 |
+---------+---------+---------+
| 1 | qq | 23 |
| 2 | ee | 12 |
| 3 | dd | 123 |
+---------+---------+---------+
3 rows selected (0.139 seconds)
0: jdbc:phoenix:maxiqtesting1.lti.com:2181:/h>
创建配置单元表命令:
CREATE EXTERNAL TABLE HBASE_TEST_6JULY(FIELD0 int,FIELD1 string, FIELD2 int)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,0:FIELD1,0:FIELD2","hbase.table.default.storage.type" = "binary", 'serialization.format'='1')
TBLPROPERTIES("hbase.table.name" = "HBASE_TEST_6JULY_1792409");
配置单元表上的select命令给出如下结果:
hive> select * from HBASE_TEST_6JULY;
OK
-2147483647 qq -2147483625
-2147483646 ee -2147483636
-2147483645 dd -2147483525
Time taken: 0.963 seconds, Fetched: 3 row(s)
整列值显示不正确。如果我在配置单元中将所有列作为字符串,那么在hbase中对应的整数列将为null
有谁能帮助我,通过在hbase上公开配置单元表来提供读取具有正确值的数字/非字符串列的解决方案吗?

要从hbase读取非字符串列,ddl语句应该
注意在int列的列Map限定符中使用了“#b”。这帮我修好了。
