How does Hue decide Impala Node as Coordinator

avatar
Expert Contributor

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?

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.
