What does the operator -i do in `impala-shell -i localhost`

As per impala documentation, you start impala shell using this command

$ impala-shell -i localhost --quiet

Any idea what -i does? and why we needed?

Ok,

I think I found the answer.

By default impala-shell connect to localhost. So by only doing

$ impala-shell

This is going to go to the default impala host, port 21000

[localhost:21000] >

In case you are you want to manage impala in a cluster or a remote server you should specify a host by using the operator -i

such as impala-shell -i host.yourdomain.com

[host.yourdomain.com:21000] >

Or to a different port

such as impala-shell -i host.yourdomain.com:26000

[host.yourdomain.com:26000] >
