[jira] [Commented] (KYLIN-3066) cleanup job's intermediate hdfs file belong to very old segment

    [ https://issues.apache.org/jira/browse/KYLIN-3066?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16272691#comment-16272691 ]

-------------------------------------

+1
The top level segments (like yearly) won't be merged, keeping the cuboid files on HDFS is wasteful.

> 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
