FAQ
When running a select query from the impala-shell, I'm getting the
following exception (hive queries work fine on this table):

ERROR: com.google.common.util.concurrent.UncheckedExecutionException:

Impala has been installed from Cloudera Manager Free Edition.

Here's some configuration:

cat

-fe_port=21000
-be_port=22000

-hostname=hadoop0.ourdomain.com
-state_store_host=hadoop0.ourdomain.com
-state_store_port=24000
-nn=hadoop0.ourdomain.com
-nn_port=8020
