Beeline连接
WARNING: Hive CLI is deprecated and migration to Beeline is recommended.
贴心翻译：
警告：不建议使用Hive CLI，建议迁移到Beeline
小伙伴们启动hive的时候是不是经常会有上面那个警告，让人看着非常的不爽
[wzj@hadoop001 ~]$ hive

既然不建议我们使用hive CLI 建议使用Beeline连接，那我们就听话试一下吧
首先我们启动下HS2的服务吧
[wzj@hadoop001 bin]$ ./hiveserver2
Beeline连接，启动客户端
命令：./beeline -u jdbc:hive2://host:10000/metadata -n use
[wzj@hadoop001 bin]$ ./beeline -u jdbc:hive2://hadoop001:10000/data_hive -n wzj
which: no hbase in (/home/wzj/app/hive/bin:/home/wzj/app/hadoop/bin:/home/wzj/app/hadoop/sbin:/usr/java/jdk1.8.0_45/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/wzj/.local/bin:/home/wzj/bin)

Beeline version 1.1.0-cdh5.16.2 by Apache Hive

ok!没有问题 链接成功 没有那个警告了
客户端来执行一条命令：show databases;

我们可以看到服务端会有多了一条ok
[wzj@hadoop001 bin]$ ./hiveserver2

OK
修改默认端口
上面Beeline连接默认端口号是10000,我们可不可以换成其它的呢？
官网参数如下：
hive.server2.thrift.port
Default Value: 10000
那我们修改一下试试
[wzj@hadoop001 bin]$ hiveserver2 --hiveconf hive.server2.thrift.port=10086
which: no hbase in (/home/wzj/app/hive/bin:/home/wzj/app/hadoop/bin:/home/wzj/app/hadoop/sbin:/usr/java/jdk1.8.0_45/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/wzj/.local/bin:/home/wzj/bin)
WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
如下，连接10000端口报错，10086成功
[wzj@hadoop001 bin]$ ./beeline -u jdbc:hive2://hadoop001:10000/data_hive -n wzj
which: no hbase in (/home/wzj/app/hive/bin:/home/wzj/app/hadoop/bin:/home/wzj/app/hadoop/sbin:/usr/java/jdk1.8.0_45/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/wzj/.local/bin:/home/wzj/bin)

dbeaver 连接
1.后台启动metastore服务和hiveserver2服务
[wzj@hadoop001 conf]$ cd
[wzj@hadoop001 ~]$ nohup hive --service metastore > ~/log/metastore.log 2>&1 &
[1] 4339
[wzj@hadoop001 ~]$ nohup hiveserver2 > ~/log/hiveserver2.log 2>&1 &

2.拷贝如下两个jar包到windows上
3.dbeaver创建连接，添加两个jar包
