回复： A question about the start date of cube in Kylin
hi, shaofeng,
I manually modify cube's definition, while when I buid the cube using REST API, it doesn't work.
In the log I found the following exception.
I found that the new segment must started from the existing segments' end date(JobService):
In this situation, how could I build a segment before existing segments, says 20160101~20160401?

You can use the metadata tool to manually modify cube's definition (change
start date to 20160101), after that, trigger a build job for 20160101 -
20160401 from REST API (not from web GUI). Manually edit the cube metadata
isn't recommended, but it can solve such case.

maybe you can try this: also use the metadata tool, manually change the
first segment's start time from 20160401 (both the "name" and "
dateRangeStart") to the very begining 20160101, restore the change to HBase
metastore; and then refresh the first segment, it will retrieve the data
since 20160101. After finish, your cube will have the data of this year.
BTW, we don't suggest to manually edit metadata, unless you're very clear
and careful about what you're doing. Backup is always needed.
