hive and hbase integration case, demo

The hive and hbse environments have been set up
1. Add attributes in the hive-site.xml configuration file of the hive server:

  <property>
    <name>hbase.zookeeper.quorum</name>
    <value>node001,node002,node003</value>
  </property>

After the increase is as follows

<configuration>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/user/hive/warehouse</value>
</property>
<property>
<name>hive.metastore.local</name>
<value>true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://node001/hive?createDatabaseIfNotExist=true</value>
</property>

<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>

<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>root</value>
</property>

<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>123</value>
</property>
  <property>
    <name>hbase.zookeeper.quorum</name>
    <value>node001,node002,node003</value>
  </property>
</configuration>

2. Test

启动hbase：start-hbase.sh 
启动hive服务端:hive --service metastore

Create a table and insert data in hbase

create 'student','stuinfo';
put 'student','0001', 'stuinfo:name','zhangsan';
put 'student','0001', 'age','22';
put 'student','0002', 'stuinfo:name','lisi';
put 'student','0002', 'age','33';

Create a table on the hive side and create a hbase field mapping

create external table student(
        id string,
        name string,
        age string
)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,stuinfo:name,stuinfo:age")
TBLPROPERTIES("hbase.table.name" = "student")

The query results in hive are as follows

hive> select * from student;
OK
0001    zhangsan        22
0002    lisi    33
