-----------------------------
Summary: Change build engine smoothly
Key: KYLIN-2950
URL: https://issues.apache.org/jira/browse/KYLIN-2950
Project: Kylin
Issue Type: Bug
Affects Versions: v2.0.0
Reporter: fengYu
Assignee: fengYu
Currently, we can not change build engine without disable cube and purging all
existing segments. But it is expensive。
After my test building cube with MR engine and Spark engine, there generate the
same result, and Merge job always use mr engine. Hence, I think take engineType
as a part of cube's Signature is improper。
I change the code and modify cube json. it work will with MR and spark engine
Alternately。
TO BE DONE：modify web UI.
