Hive thrift服务(将Hive作为一个服务器,其他机器可以作为客户端进行访问)

 步骤一:启动为前台:bin/hiveserver2

步骤二:启动为后台:nohup bin/hiveserver2 1>/var/log/hiveserver.log 2>/var/log/hiveserver.err &

1:启动成功后,可以在别的节点上用beeline去连接

  方式一:

    hive/bin/beeline  回车,进入beeline的命令界面

    输入命令连接hiveserver2

    beeline> !connect jdbc:hive2//master:10000

    (master机器是hiveserver2所启动的那台主机名,端口默认是10000

  方式二:

    或者启动就连接:

    bin/beeline -u jdbc:hive2://master:10000 -n hadoop

接下来就可以做正常sql查询了

1:将Hive作为一个服务器,其他机器可以作为客户端进行访问:

 Hive thrift服务(将Hive作为一个服务器,其他机器可以作为客户端进行访问)

2:然后寻找符合thrift的这种协议的客户端来连这个服务,然而hive自带这种客户端(我这里复制本台机器,弄了两个窗口):

 Hive thrift服务(将Hive作为一个服务器,其他机器可以作为客户端进行访问)

然后呢,就是开启了命令行客户端了,然后了连接你的hive即可。我这里遇到一个错误,顺手贴一下吧。

 造成这个错误的原因是!connect jdbc:hive2//master:10000写成!connect jdbc:hive2//localhost:10000即可。

 1 [root@master apache-hive-1.2.1-bin]# cd bin/
 2 [root@master bin]# ls
 3 beeline  ext  hive  hive-config.sh  hiveserver2  metatool  schematool
 4 [root@master bin]# ./beeline 
 5 Beeline version 1.2.1 by Apache Hive
 6 beeline> !connect jdbc:hive2//master:10000
 7 scan complete in 1ms

11 scan complete in 5708ms
12 No known driver to handle "jdbc:hive2//master:10000"

然后呢我写成beeline> !connect jdbc:hive2://localhost:10000回车。会让你输入账号和密码,这里直接输入你的登陆linux的账号和密码即可,我习惯使用root和其密码操作,虽然不好,但是这里直接输入root账号,123456密码即可登陆。
