[jira] [Updated] (KYLIN-2442) Re-calculate expansion rate, count raw data size regardless of flat table compression

     [ https://issues.apache.org/jira/browse/KYLIN-2442?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

liyang updated KYLIN-2442:
--------------------------
    Description: Right now the expansion rate is calculated as "Cube Size / Raw Data Size". And the raw data size is the size of intermediate hive table. This causes the Raw Data Size depending on the compression format of the intermediate table. And affects the correctness of expansion rate and the estimates based on the raw data size.
