Symptom:

Impala query from Hue failed with error message:

Invalid method name: 'OpenSession'

Root cause:

Impala uses 21000 port to communicate commands and receive results through the impala-shell and the ODBC driver.
Impala uses 21050 port to communicate commands and receive results through applications.
However in hue.ini, "server_port=21000" is set.

Solution:

Change "server_port=21000" to "server_port=21050" in hue.ini, and then restart the 'hue' service.
