问题导读:
1.hive安装是否需要安装mysql?
2.hive是否分为客户端和服务器端?
3.hive的元数据库有哪两种?
4.hive与hbase整合的关键是什么?
5.hive的安装是否必须安装hadoop?
6.hive与hbase整合需要做哪些准备工作?
7.hive元数据库启动卡住代表的含义是什么?
网上有很多资料,看到大部分都是一致的,看到一篇国外的文章,原来都是翻译的,并没有经过实践。这里记录一下实践的过程。
本篇是在:
hadoop2.2完全分布式最新高可靠安装文档
http://www.aboutyun.com/thread-7684-1-1.html
hbase 0.96整合到hadoop2.2三个节点全分布式安装高可靠文档
http://www.aboutyun.com/thread-7746-1-1.html
基础上的一个继续:
因为derby数据库使用的局限性,我们采用mysql作为元数据库。
derby存在什么缺陷
1.derby不能多个客户端登录
2.derby登录必须在相同目录下,否则可能会找不到所创建的表。
比如在/hive目录下启动hive程序,那么所创建的表就会存储在/hive下面保存。如果在/home下面,所创建的表就会在/home下面保存。这样导致初学者摸不着头脑。如果还不是不太明白可以,可以参考

hive使用derby作为元数据库找达到所创建表的原因
http://www.aboutyun.com/thread-7803-1-1.html
-----------
下面我们开始安装:
1.下载hive
链接: http://pan.baidu.com/s/1eQw0o50 密码: mgy6
2. 安装:
tar zxvf hive-0.12.0.tar.gz
重命令名为:hive文件夹
达到如下效果:
3. 替换jar包,与hbase0.96和hadoop2.2版本一致
由于我们下载的hive是基于hadoop1.3和hbase0.94的,所以必须进行替换,因为我们的hbse0.96是基于hadoop2.2的,所以我们必须先解决hive的hadoop版本问题,目前我们从官网下载的hive都是用1.几的版本编译的,因此我们需要自己下载源码来用hadoop2.X的版本重新编译hive,这个过程也很简单,只需要如下步骤:
(1)进入/usr/hive/lib
上面只是截取了一部分:
(2)同步hbase的版本
先cd到hive0.12.0/lib下,将hive-0.12.0/lib下hbase-0.94开头的那两个jar包删掉,然后从/home/hadoop/hbase-0.96.0-hadoop2/lib下hbase开头的包都拷贝过来
find /usr/hbase/hbas/lib -name "hbase*.jar"|xargs -i cp {} ./
(3)基本的同步完成了
重点检查下zookeeper和protobuf的jar包是否和hbase保持一致,如果不一致,
拷贝protobuf.**.jar和zookeeper-3.4.5.jar到hive/lib下。
(4)用mysql当原数据库,
找一个mysql的jdbcjar包mysql-connector-java-5.1.10-bin.jar也拷贝到hive-0.12.0/lib下
可以通过下面命令来查找是否存在
如果不存在则下载:
链接: http://pan.baidu.com/s/1gdCDoGj 密码: 80yl
--------------------------------------------------------------------------
注意 mysql-connector-java-5.1.10-bin.jar
修改权限为777 (chmod 777 mysql-connector-java-5.1.10-bin.jar)
--------------------------------------------------------------------------
还有,看一下hbase与hive的通信包是否存在:
可以通过下面命令:
aboutyun@master:/usr/hive/lib$ find -name hive-hbase-handler*
./hive-hbase-handler-0.13.0-SNAPSHOT.jar
不存在则下载:
链接: http://pan.baidu.com/s/1gd9p0Fh 密码: 94g1
4. 安装mysql
• Ubuntu 采用apt-get安装
• sudo apt-get install mysql-server
• 建立数据库hive
• create database hivemeta
• 创建hive用户,并授权
• grant all on hive.* to hive@'%' identified by 'hive';
• flush privileges;
对于musql的安装不熟悉,可以参考:
Ubuntu下面卸载以及安装mysql
http://www.aboutyun.com/thread-7788-1-1.html
-------------------------------------------
上面命令解释一下:
• sudo apt-get install mysql-server 安装数据服务器,如果想尝试通过其他客户端远程连接,则还需要安装mysql-client
• create database hivemeta
这个使用来存储hive元数据,所创建的数据库
• grant all on hive.* to hive@'%' identified by 'hive'; 这个是授权,还是比较重要的,否则hive客户端远程连接会失败
里面的内容不要照抄:需要根据自己的情况来修改。上面的用户名和密码都为hive。
如果连接不成功尝试使用root用户
grant all on hive.* to 'root'@'%'identified by '123';
flush privileges; 复制代码
------------------------------------------
4. 修改hive-site文件配置:
下面配置需要注意的是:
(1)使用的是mysql的root用户,密码为123,如果你是用的hive,把用户名和密码该为hive即可:
(2)hdfs新建文件并授予权限
对于上面注意
bin/hadoop fs -mkdir /hive/warehouse
bin/hadoop fs -mkdir /hive/scratchdir
bin/hadoop fs -chmod g+w /hive/warehouse
bin/hadoop fs -chmod g+w /hive/scratchdir
(3)hive.aux.jars.path切忌配置正确
不能有换行或则空格。特别是换行,看到很多文章都把他们给分开了,这对很多新手是一个很容易掉进去的陷阱。
<property>
<name>hive.aux.jars.path</name>
<value>file:///usr/hive/lib/hive-hbase-handler-0.13.0-SNAPSHOT.jar,file:///usr/hive/lib/protobuf-java-2.5.0.jar,file:///usr/hive/lib/hbase-client-0.96.0-hadoop2.jar,file:///usr/hive/lib/hbase-common-0.96.0-hadoop2.jar,file:///usr/hive/lib/zookeeper-3.4.5.jar,file:///usr/hive/lib/guava-11.0.2.jar</value>
</property> 复制代码
上面问题解决,把下面内容放到hive-site文件即可
--------------------------------
这里介绍两种配置方式,一种是远程配置,一种是本地配置。最好选择远程配置
远程配置
<configuration>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>hdfs://master:8020/hive/warehouse</value>
</property>
<property>
<name>hive.exec.scratchdir</name>
<value>hdfs://master:8020/hive/scratchdir</value>
</property>
<property>
<name>hive.querylog.location</name>
<value>/usr/hive/logs</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://172.16.77.15:3306/hiveMeta?createDatabaseIfNotExist=true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>
<property>

<value>hive</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
</property>
<property>
<name>hive.aux.jars.path</name>
<value>file:///usr/hive/lib/hive-hbase-handler-0.13.0-SNAPSHOT.jar,file:///usr/hive/lib/protobuf-java-2.5.0.jar,file:///usr/hive/lib/hbase-client-0.96.0-hadoop2.jar,file:///usr/hive/lib/hbase-common-0.96.0-hadoop2.jar,file:///usr/hive/lib/zookeeper-3.4.5.jar,file:///usr/hive/lib/guava-11.0.2.jar</value>
</property>
<property>
<name>hive.metastore.uris</name>
<value>thrift://172.16.77.15:9083</value>
</property>
</configuration> 复制代码
本地配置:
<configuration>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/user/hive_remote/warehouse</value>
</property>
<property>
<name>hive.metastore.local</name>
<value>true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost/hive_remote?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>
</configuration> 复制代码
-------------------------------------------------------------------------------------
5. 修改其它配置:
1.修改hadoop的hadoop-env.sh(否则启动hive汇报找不到类的错误)
2.修改$HIVE_HOME/bin的hive-config.sh,增加以下三行
然后我们首先启动元数据库hive --service metastore -hiveconf hive.root.logger=DEBUG,console 复制代码
记得这里它会卡住不动,不用担心,这里已经启动成功。
然后我们在启动客户端
复制代码
这样hive就安装成功了
首先说一些遇到的各种问题
1.遇到的问题
问题1:元数据库未启动
这里首先概括一下,会遇到的问题。首先需要启动元数据库,通过下面命令:
(1)hive --service metastore
(2)hive --service metastore -hiveconf hive.root.logger=DEBUG,console
注释:
-hiveconf hive.root.logger=DEBUG,console命令的含义是进入debug模式,便于寻找错误
如果不启用元数据库,而是使用下面命令
复制代码
你会遇到下面错误

刚开始遇到这种情况,我知道是因为可能没有配置正确,这个耗费了很长时间,一直没有找到正确的解决方案。当再次执行
hive --service metastore
命令的时候报4083端口被暂用: 报错如下红字部分。表示9083端口已经被暂用,也就是说客户端已经和主机进行了通信,当我在进行输入hive命令的时候,进入下面图1界面

对于端口的暂用,可以采用下面命令杀掉进程

验证hive与hbase的整合:
一、启动hbase与hive
启动hbase
复制代码
启动hive
(1)启动元数据库
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" = "xyz"); 复制代码
上面的含义是在hive中建表hbase_table_1, 通过org.apache.hadoop.hive.hbase.HBaseStorageHandler这个类映射,在hbase建立与之对应的xyz表。
(1)执行这个语句之前:
首先查看hbase与hive:
hbase为空:
hive为空
(2)执行
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" = "xyz"); 复制代码
(3)对比发生变化
hbase显示新建表xyz
hive显示新建表hbase_table_1
三、验证整合,在hbase插入表
(1)通过hbase添加数据
在hbase中插入一条记录:
put 'xyz','10001','cf1:val','www.aboutyun.com' 复制代码
分别查看hbase与hive表发生的变化:
(1)hbase变化
(2)hive变化
(2)通过hive添加数据
对于网上流行的通过pokes表,插入这里没有执行成功,通过网上查询,可能是hive0.12的一个bug.详细可以查看:
INSERT OVERWRITE TABLE hbase_table_1 SELECT * FROM pokes;
