This is a development issue that needs no QA verification.

> Drill provides a wide variety of unit tests. Many derive from {{PopUnitTestBase}} to
test the Physical OPerators.
> The tests use a default configuration:
> {code}
> protected static DrillConfig CONFIG;
>   @BeforeClass
>   public static void setup() {
>     CONFIG = DrillConfig.create();
>   }
> {code}
> The tests rely on config settings specified in the {{pom.xml}} file (see note below.)
When run in Eclipse, no such config exists, so the tests use only the default config. The
defaults allow a web server to be started.
> Many tests start multiple Drillbits using the above config. When this occurs, each tries
to start a web server. The second one fails because the HTTP port is already in use.
> The solution is to initialize the config using the same settings as used in the {{BaseTestQuery}}
test case: the unit tests then work fine in Eclipse.
> As an aside, having multiple ways to set up the Drill config (and other items) leads
to much wasted time as each engineer must learn the quirks of each test hierarchy.
