Eugene Koifman commented on HIVE-8367:
--------------------------------------
I think this needs more info. What was the original query where the issue
showed up?
What precisely was the problem and how does the RS deduplication change help?
The explanation for the latter would be useful to add to the code where this
setting is set.
How is the changes to sort order of ROW__ID related?
> delete writes records in wrong order in some cases

> I have found one query with 10k records where you do:
> create table
> insert into table -- 10k records
> delete from table -- just some records
> The records in the delete delta are not ordered properly by rowid.
> I assume this applies to updates as well, but I haven't tested it yet.
