需要对访问hive做用户密码验证,网上搜了下要自己重写接口,并做如上的配置,重启后发现根本就没生效啊,随便输个用户和密码都能进去。
开始以为是配置错了地方,然后把client端和server端,server2都配置了还是没有任何反应(用的cdh,配置有分client端server端),下面是根据网上教程copy来的验证代码。各位大大帮忙看下,是哪里出问题了。

额,配置在server端时链接有报错:
[cloudera@quickstart hive]$ beeline

Unexpected end of file when reading from HS2 server. The root cause might be too many concurrent connections. Please ask the administrator to check the number of active connections, and adjust hive.server2.thrift.max.worker.threads if applicable.

我用的是自己的虚拟机,就我一个人用户,所以应该不存在链接过多(链接数配置的1000)
