Zoltan Haindrich commented on HIVE-18237:
-----------------------------------------
well..all I know is: in the above {{insert overwrite}} case the data
layout(physically) seems like to be the "non-mm" version; this could be fixed
in 2 ways:
* like patch#01; correct somehow the partition scanning logic to do the right
type of scan
* correct the writers to use the layout which this method is expecting.
if the latter is the preferred...then I've to say that: I'm not sure how to do
that; so feel free to take it over.... :)

> explain insert overwrite table p0 partition (p) select * from i0 where v < 3;
> insert overwrite table p0 partition (p) select * from i0 where v < 3;
> select count(*) from p0 where v!=1;

> The table p0 should contain {{2}} rows at this point; but the result is {{0}}.
> * seems to be specific to insert_only tables
> * the existing data appears if an {{insert into}} is executed.
