Description

After KYLIN-1966, user can't see generated SQL at cube page.

2016-10-10 15:45:17,975 ERROR [http-bio-8080-exec-13] controller.BasicController:44 :
java.lang.NullPointerException
        at org.apache.kylin.engine.EngineFactory.batchEngine(EngineFactory.java:44)
        at org.apache.kylin.engine.EngineFactory.getJoinedFlatTableDesc(EngineFactory.java:58)
        at org.apache.kylin.rest.controller.CubeController.getSql(CubeController.java:155)

Seems segmentName passed into CubeController#getSql is always null, should use `EngineFactory.getJoinedFlatTableDesc(cube.getDescriptor())` instead.
