答复: 答复: Kylin2.5 - org.apache.catalina.LifecycleException: Failed to start component

2018-12-26 Thread Na Zhai 
Hi, CookieNats.



   Have you run the bin/sample.sh? In this script, "engine_type" and 
"storage_type" will be set. If it does not work, it may be your env has the 
problem. You can modify the script or modify the kylin_sales_cube.json as the 
article saying. That is a good way. After you run Kylin in the right way. You 
can change the "engine_type" in Model -> Cube Designer -> Advanced Setting page.



   Best wishes!

Hi kylin-dev,


在您的指导下经过一段时间摸索和尝试我本地的kylin已经启动起来，导入sample例子，不过遇到一个问题，例子中kylin_sales_cube.json里有一个环境变量导致load
cube的时候介些json出错，所以麻烦告知一下这个参数应该在哪里设置，并在在网上看到里相同问题：https://blog.csdn.net/u010429286/article/details/72722597，不过他是使用修改json的方式解决的。

"engine_type" : %default_engine_type%,
"storage_type" : %default_storage_type%

感谢kylin团队的支持

Re: 答复: show the kylin sql for timeout

2018-12-26 Thread JiaTao Tao 
At present, Kylin's min "kylin.query.timeout-seconds" is 60s, and you can
not set this smaller.

If you want to simulate the scenario of timeout, you can take a look at
"ITKylinQueryTest#testTimeoutQuery". It uses a hack way, see:
"org.apache.kylin.gridtable.StorageSideBehavior#SCAN_FILTER_AGGR_CHECKMEM_WITHDELAY".
But I do not recommend this cuz it seems just for developing and it is too
hacky.

By the way, Kylin's timeout exception is: KylinTimeoutException. And
there's a test mocked this scenario:
"org.apache.kylin.rest.service.KylinQueryTimeoutTest". May this can help
you.

Re: show the kylin sql for timeout

2018-12-26 Thread yiifeger wu 
Hi, Yunyao,
maybe u could set a small timeout value in the Kylin.properties, then it
should be okay to get a TimeoutException

Hi, yunyao.

   Is that you mean you want to see the phenomenon of SQL query timeout? 
Why do you want to do that? Or you just want to know the value of timeout?
