Zhong Yanghong updated KYLIN-2905:
----------------------------------
Description: In cases hbase is very busy, it cost some time to put all of
the job related metadata into hbase. The job related metadata includes job info
and job output info. Currently, kylin put job info into hbase first, then job
output info. If server is down and only part of job output info has been put
into hbase during this period, kylin will fail to load job when restarts.
(was: It's a common requirement that user wants to upgrade an existing cube by
adding a column which is not in its referred model. To deal with this
requirement, it's better to add model compatibility check to allow compatible
model changes.)
