> Hi all:
> We know that kylin's build job often runs late at night, so calling
> kylin's restful API directly is a very common thing. In this scenario, if
> the startTime is equal to the endTime, something unexpected will happen. The
> job calculates all partition data, so the query result is wrong.
> For example, when I send the following request to kylin.
> curl -X PUT -H "Authorization: Basic XXXXXXX" -H 'Content-Type:
> application/json' -d '\{"startTime":'1541894400000',
> "endTime":'1541894400000', "buildType":"BUILD"}'
> [http://xxxxxx:xxxx/kylin/api/cubes/cube_name/build|http://xxxxxxxxxx/]
> then, the job will calculate all partition data. I find the backend interface
> of build lacks checksum data range, and the sql of generating the flat table
> is wrong.
> I try to fix this bug, and the patch is in the attachment.
