Eugene Koifman commented on HIVE-18739:
---------------------------------------
The temp table is created and populated by the user who submits the Export
command.
A meaningful default security policy would be configured so that this table is
only readable by the user creating it in which case there is no issue. If the
default is for all objects to fully public then the problem lies with that.
Regarding compaction, exporting any file produced by it will have ROW_IDs
embedded in it. These do not make sense in a different table/cluster w/o all
the metadata in the metastore.
> Add support for Export from Acid table
