Subject 回复: 答复: Re: Kylin Count(col) Result Is Different With Hive
Date Tue, 23 Oct 2018 08:01:25 GMT
Hi Shaofeng,
   I didn't find this configuration parameter in the configuration list via,
could you help to check that?

Besides, could this configuration be overwritten in the Cube Level? I tried this configuration
in the Cube level, but it did not works on the result of count(column). Moreover, I re-builded
this cube also, but it did not work still.

One suggestion, such new feature should be enabled by default; Otherwise, most people won't
know it, even we add it to the configuration list...

You may set the configuration 'kylin.query.enable-dynamic-column' to true in,
and test it.

Hi Ma Gang, 


   Thank you for your reply.   The column ‘fzy_bill_code’ is from fact table. 

   But what do you mean about ‘enable dynamic column configuration.”

Is the column 'fzy_bill_code' from fact table? If so, the issue should have been fixed in, you need to enable dynamic column configuration.

Hi all,  


   Run the same sql on kylin and hive, but got different result.    It seems kylin has count
NULL as 1, but hive count it as 0. 


   The sql is as below: 

     select  count(fzy_bill_code) from gjst.sh_fetch_sale_base_fact where dates between '2018-09-01'
and '2018-10-18'


   The result on kylin is :  2889422  ,  but 2688289 on hive.     


      Anyone who knows the solution for this?   Thanks a lot.
