Key: KYLIN-3689
URL: https://issues.apache.org/jira/browse/KYLIN-3689
Project: Kylin
Issue Type: Bug
Components: Job Engine, Metadata, Query Engine
Affects Versions: v2.5.0, v2.4.0

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.
