Get Impala BE Tests running for RecordService

Because we use a lot of the Impala BE code, we should also run their unit tests. I am going to use this as an umbrella JIRA; one task will be to run the tests that already pass, and we can add subtasks for each individual test that we think we should be running.

The list of passing and failing tests can be found here:
