we have some problems in using kylin api:1 the wipe cache doesn't work,we want
to 'drop' the 'kylin_sales_cube',the response status_code was 200,but the cube
is still ready2 we want to build job by hour, and there were a dozen of
cubes,so the jobs were building parallelly,how to manage these jobs,is there a
api that can tell us all the jobs' status,instead of only one job?在使用kylin
api的时候我们遇到了一些问题：1 wipe cache好像不起作用，在drop cube时，即使返回的 response
status_code是200，cube没有被删除2 如果想要每个小时都增量构建streaming
cube，并且有几十个cube都需要这样做，那么并发的job会很多，会造成OOM或者job pending吗？我们如何用api来监控所有job的状态，像web
UI中的monitor那样，有返回所有job status的API吗？目前好像只有返回指定的job status的API。
