Description

Kylin allows user to configure "kylin.query.scan.threshold" in kylin.properties, and the default value is 10 million; But in org.apache.kylin.storage.StorageContext, it has a hard-coded "HARD_THRESHOLD" which is 4 million, and "kylin.query.scan.threshold" couldn't exceed this threshold, this is wrong.

The correct behavior should be, remove HARD_THRESHOLD and always use "kylin.query.scan.threshold" as the threshold.
