How does Hue decide Impala Node as Coordinator

Hi,

I'm currently not using a Proxy forimpala (I am looking to in the near future).  I've noticed that most times my host-01 takes on the role as the co ordinator when uses run queires in hue.  This is the same host which I have the ODBC pointing too.

I'd like hue to chose a different host to use as the coordinator, is this possible?  How does Hue decide which host should beome the coordniator?

Re: How does Hue decide Impala Node as Coordinator

If you check the hue.ini file, which is the configuration for Hue, you can find below impala section:

[impala]
server_host={impala-daemon-host-url}
server_port=21050
impala_principal=impala/{impala-daemon-host-url}
impersonation_enabled=True
server_conn_timeout=120

You can see that to update Hue to connect to a different impala, you can update value for server_host.
