Shaofeng SHI commented on KYLIN-3066:
-------------------------------------
+1
The top level segments (like yearly) won't be merged, keeping the cuboid files
on HDFS is wasteful.
> cleanup job's intermediate hdfs file belong to very old segment

> Currently, the job intermediate file won't be deleted if it belongs to a
> segment which is 1 year ago . It is very waste. We should supply a config to
> define old seg and which cannot be merged , so the old seg can be deleted
