Hive与HBase的集成

第一步

在hive-site.xml文件中配置zookeeper，hive通过这参数的配置去连接HBase

        <property>
                <name>hbase.zookeeper.quorum</name>
                <value>node1,node2,node3</value>
        </property>

第二步

将HBase中的9个包拷贝到hive/lib目录下

scp hbase-client-1.2.0-cdh5.9.3.jar 
hbase-common-1.2.0-cdh5.9.3.jar 
hbase-hadoop2-compat-1.2.0-cdh5.9.3.jar 
hbase-hadoop-compat-1.2.0-cdh5.9.3.jar 
hbase-it-1.2.0-cdh5.9.3.jar 
hbase-protocol-1.2.0-cdh5.9.3.jar 
hbase-server-1.2.0-cdh5.9.3.jar 
high-scale-lib-1.1.1.jar 
htrace-core-3.2.0-incubating.jar /opt/Hadoop/hive/lib

第三步

创建与HBase集成的Hive的外部表

hive (default)> CREATE EXTERNAL TABLE weblogs(     
              > id string,
              > datatime string,
              > userid string,
              > searchname string,
              > retorder string,
              > cliorder string,
              > cliurl string 
              > )
              > STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
              > WITH SERDEPROPERTIES (
              > "hbase.columns.mapping" = 
              > ":key,info:datatime,info:userid,info:searchname,info:retorder,info:cliorder,info:cliurl")
              > TBLPROPERTIES ("hbase.table.name" = "weblogs");
OK
Time taken: 1.267 seconds

CREATE EXTERNAL TABLE weblogs(id string,datatime string,userid string,searchname string,retorder string,cliorder string,cliurl string) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,info:datatime,info:userid,info:searchname,info:retorder,info:cliorder,info:cliurl") TBLPROPERTIES ("hbase.table.name" = "weblogs");
