Shaofeng SHI updated KYLIN-1020:
--------------------------------
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.
