-----------------------------------------------------------------
There're two issues.
# One is related to JIRA [KYLIN-3022 |
https://issues.apache.org/jira/browse/KYLIN-3022], we shouldn't change the
memory state of cube segment until the data is updated to database. Otherwise
when the concurrent issue happens, the state failed to update will lead to
[~yanghaogn]'s issue
# Another issue may relate to the concurrent issue among
{{calculateToBeSegments}} and {{updateCube}}. Current solution is to add a lock
for this block.
