(Ignore my previous response - I'm editing this as I responded to the wrong thread).
Can you see if the services are running? And restart them if not? The following services need to be running (and started in this order, if the impala-state-store service fails for some reason, impala-server will also fail).
impala-catalog
impala-state-store
impala-server
So for example, 'sudo service impala-state-store status', so see if that service is running, and if it's not, try 'sudo service impala-state-store restart' and 'sudo service impala-server restart' to get things running again. If you continue to have issues, have a look at the logs in /var/log/impala for any errors that indicate why they're not starting.
