-----------------------------------
Summary: Make the create hive steps configurable (two options)
Key: KYLIN-2004
URL: https://issues.apache.org/jira/browse/KYLIN-2004
Project: Kylin
Issue Type: Improvement
Components: Job Engine
Affects Versions: v1.5.3
Reporter: Shaofeng SHI
Assignee: Shaofeng SHI
Fix For: v1.5.4
In 1.5.3 for KYLIN-1677, Kylin changed the steps when pull data from hive as:
1) count the source table 2) create intermediate flat table with redistribution
(reducer number is determined by step1)
This works good for many cases, but may not benefit for case like a view (which
joins several tables) as the fact table.
So it is better to keep the other option: 1) create intermediate flat table 2)
count the intermediate table 3) redistribute it based on the output of step 2)
Plan to make this configurable (system level & cube level).
