Description

When HiveServer2 comes up, it skips the start of the WebUI if
1) hive.in.test is set to true
AND
2) the WebUI port is not specified or default (hive.server2.webui.port)
 
Right now, on LLAP daemon start, it is only checked if hive is in test (condition 1) above.
 
The LLAP Daemon start up code (to skip WebUI creation) should be consistent with HS2, therefore if a port is specified (other than the default), the WebUI should also be started in test mode.
