Kaige Liu commented on KYLIN-2987:
-----------------------------------
Hi [~yaho], seems this patch does not work. According to
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML#LanguageManualDML-InsertOverwrite
auto.purge=true only works for MANAGED table, but KYLIN intermediate hive
tables are created as EXTERNAL table.
> Skip moving to Trash when drop an intermediate hive table or redistribute a
> hive table

> 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.
