Hadoop 使用SIMBA的Impala ODBC连接

我参考了Simba/CDH提供的Impala ODBC连接并安装了它。我正在使用CDH5.3和Impala 2.1.0

在odbc.ini中，我尝试了端口2105021000，但无法连接到Impala。后来我使用了端口10000并能够连接。不确定这个端口是否真的像我在isql-v Impala_simba上运行'select count*from emp'时那样在Impala中运行查询，与从Impala shell中运行相同的查询相比，它需要很多时间。 我怀疑配置是否真的使用黑斑羚或蜂巢？ 我还尝试使用CDH提供的Impala ODBC连接，但也存在同样的问题

您能告诉我在.odbc.ini中应该提到的正确的Impala端口是什么，以便它在Impala中运行查询吗

这里是配置

问题解决了。使AuthMech=0并删除UID，因为远程客户端将在没有身份验证的情况下连接到Impala。请澄清一下，您是说通过身份验证可以连接，但性能很慢，而没有身份验证的情况下性能很快吗？
