hive beeline使用说明

参考 https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-PythonClient

https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2#SettingUpHiveServer2-PythonClientDriver

Example:
1. Connect using simple authentication to HiveServer2 on localhost:10000
$ beeline -u jdbc:hive2://localhost:10000 username password

2. Connect using simple authentication to HiveServer2 on hs.local:10000 using -n for username and -p for password
$ beeline -n username -p password -u jdbc:hive2://hs2.local:10012

3. Connect using Kerberos authentication with hive/localhost@mydomain.com as HiveServer2 principal  （现在一般生产集群都是用Kerberos 认证）
$ beeline -u "jdbc:hive2://hs2.local:10013/default;principal=hive/localhost@mydomain.com

4. Connect using SSL connection to HiveServer2 on localhost at 10000
$ beeline jdbc:hive2://localhost:10000/default;ssl=true;sslTrustStore=/usr/local/truststore;trustStorePassword=mytruststorepassword

5. Connect using LDAP authentication
$ beeline -u jdbc:hive2://hs2.local:10013/default <ldap-username> <ldap-password>

后面就像sql一样使用

  python client：

能装上，但是对kerberos不是很友好

这个链接是pyhive针对kerberos认证讨论的操作方法

1. Install kerberos on your own computer
2. Setup kerberos on your computer so that it connects to the remote kerberos server (/etc/krb5.conf)
3. Given a keytab file (provided by your kerberos administrator), you can authenticate your computer to the remote kerberos server using kinit -kt your.keytab username@YOUR_KERBEROS_REALM
4. You can check that you have a valid kerberos ticket using klist
5. You can now launch pyhive with kerberos.
