HBASE_HIVE整合

Posted 2020-11-07 李杰然

Hive与HBase的整合功能的实现是利用两者本身对外的API接口互相进行通信，相互通信主要是依靠hive_hbase-handler.jar工具类

首先保证版本一致

cd /home/hadoop/hive-1.1.0-cdh5.5.2/lib

查看版本是否一致hbase-server-1.0.0-cdh5.5.2.jar  zookeeper-3.4.5-cdh5.5.2.jar  hive-hbase-handler-1.1.0-cdh5.5.2.jar

如果不一致删除原有jar  cp 原hbase和zookeeper下的jar包到hive的lib中

 

2.修改 hive/conf下hive-site.xml文件
[[email protected] hive-0.7.1-cdh3u5]$ mkdir tmp
[[email protected] hive-0.7.1-cdh3u5]$ mkdir logs

[[email protected] conf]$ vi hive-site.xml
以下内容 添加到文件底部  </configuration> 之上

<!--        
<property>  
  <name>hive.exec.scratchdir</name>
  <value>/home/hadoop/hive-1.1.0-cdh5.5.2/tmp/</value>
</property>   
-->   

<property>
  <name>hive.querylog.location</name>
  <value>/home/hadoop/hive-1.1.0-cdh5.5.2/logs/</value>
</property>

<property>
  <name>hive.aux.jars.path</name>  
  <value>
    file:///home/hadoop/hive-1.1.0-cdh5.5.2/lib/hive-hbase-handler-1.1.0-cdh5.5.2.jar,
    file:///home/hadoop/hive-1.1.0-cdh5.5.2/lib/hbase-server-1.0.0-cdh5.5.2.jar,
    file:///home/hadoop/hive-1.1.0-cdh5.5.2/lib/zookeeper-3.4.5-cdh5.5.2.jar
  </value>
</property>

 

3.拷贝hbase-server-1.0.0-cdh5.5.2.jar 到所有hadoop节点 lib下（包括master节点）
[[email protected] hbase-0.90.6-cdh3u5]$ cp hbase-server-1.0.0-cdh5.5.2.jar /home/hadoop/hadoop-2.6.0-cdh5.5.2/lib
[[email protected] hbase-0.90.6-cdh3u5]$ scp hbase-server-1.0.0-cdh5.5.2.jar [email protected]:/home/hadoop/hadoop-2.6.0-cdh5.5.2/lib
[[email protected] hbase-0.90.6-cdh3u5]$ scp [email protected]:/home/hadoop/hadoop-2.6.0-cdh5.5.2/lib

4.拷贝hbase/conf下的hbase-site.xml文件到所有hadoop节点(包括master)的hadoop/conf下
[[email protected] conf]$ cp hbase-site.xml /home/hadoop/hadoop-2.6.0-cdh5.5.2/conf/
[[email protected] conf]$ scp hbase-site.xml [email protected]:/home/hadoop/hadoop-2.6.0-cdh5.5.2/conf/
[[email protected] conf]$ scp hbase-site.xml [email protected]:/home/hadoop/hadoop-2.6.0-cdh5.5.2/conf/


5.启动hive
[[email protected] hive-0.7.1-cdh3u5]$ bin/hive -hiveconf hbase.zookeeper.quorum=h201,h202,h203

----------------------------------------------------------------
例子
1创建 hbase识别的表
hive>
CREATE TABLE hbase_table_1(key int, value string)  
STORED BY ‘org.apache.hadoop.hive.hbase.HBaseStorageHandler‘  
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:val")  
TBLPROPERTIES ("hbase.table.name" = "sq");

***（hbase.table.name 定义在hbase的table名称
     hbase.columns.mapping 定义在hbase的列族）****

2.创建 hive表
hive> create table ha1(id int,name string)
     row format delimited
     fields terminated by ‘\t‘
     stored as textfile;

[[email protected] ~]$ vi ha1.txt
11      zs
22      ls
33      ww

hive> load data local inpath ‘/home/hadoop/ha1.txt‘ into table ha1;

hive> insert into table hbase_table_1 select * from ha1;

~~hive> select * from  hbase_table_1;  

3.[[email protected] hbase-0.90.6-cdh3u5]$ bin/hbase shell

hbase(main):002:0> scan ‘sq‘
（能看到结果 说明hive把数据存到hbase中）

 

第二种方法直接修改 hive/conf下hive-site.xml文件

<!--        
<property>  
  <name>hive.exec.scratchdir</name>
  <value>/home/hadoop/hive-1.1.0-cdh5.5.2/tmp/</value>
</property>   
-->   

<property>
  <name>hive.querylog.location</name>
  <value>/home/hadoop/hive-1.1.0-cdh5.5.2/logs/</value>
</property>

<property>
  <name>hive.aux.jars.path</name>  
  <value>
    file:///home/hadoop/hive-1.1.0-cdh5.5.2/lib/hive-hbase-handler-1.1.0-cdh5.5.2.jar,
    file:///home/hadoop/hive-1.1.0-cdh5.5.2/lib/guava-14.0.1.jar,
    file:///home/hadoop/hbase-1.0.0-cdh5.5.2/lib/hbase-common-1.0.0-cdh5.5.2.jar,
    file:///home/hadoop/hbase-1.0.0-cdh5.5.2/lib/hbase-client-1.0.0-cdh5.5.2.jar,
    file:///home/hadoop/hbase-1.0.0-cdh5.5.2/lib/hbase-server-1.0.0-cdh5.5.2.jar,
    file:///home/hadoop/hbase-1.0.0-cdh5.5.2/lib/netty-all-4.0.23.Final.jar,
    file:///home/hadoop/hbase-1.0.0-cdh5.5.2/lib/hbase-hadoop2-compat-1.0.0-cdh5.5.2.jar,
    file:///home/hadoop/zookeeper-3.4.5-cdh5.5.2/zookeeper-3.4.5-cdh5.5.2.jar
  </value>
</property>

然后重启hive即可。
