Re: how can i increase the count of reduce at Kylin_HFile_Generator_cubename_step?

what's your kylin version, what's the capacity of your model (small,
medium, or large), how many reducers be started in this step, and what's
the total size of the HTable?

You can reduce the value of the following parameter to let kylin split more
regions, then more reducers will be started.

kylin.hbase.region.cut.small=5
kylin.hbase.region.cut.medium=10
kylin.hbase.region.cut.large=50
