Subject [jira] [Commented] (KYLIN-2987) Add 'auto.purge=true' when creating intermediate hive table or redistribute a hive table
Date Mon, 26 Mar 2018 06:00:00 GMT

Zhong Yanghong commented on KYLIN-2987:
---------------------------------------

Hi [~liukaige], I think this issue relates to HIVE. Why auto.purge=true cannot work for EXTERNAL
tables. Currently HIVE may not support. However, for the long term, I don't know why not support
it.

> At kylin side, we can add auto.purge=true when creating intermediate table.
> However, to make ‘auto.purge’ effective for “insert overwrite table”, we still
need one patch for hive.
