Hi kyliners: I followed example in http://kylin.apache.org/docs15/tutorial/kylin_sample.html .But in step3 ，I can not build sample cube “kylin_sales_cube" ，it failed with:
There exists a build request of this cube, the job may be running or
error. If you need a new build, please wait for its complete or discard it.
But I do not find any running or error job in Kylin:
