> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.8.0

>
> When INSERT INTO is run on a table with compressed output
> (hive.exec.compress.output=true) and existing files in the table, it may copy
> the new files in bad file names:
> Before INSERT INTO:
> 000000_0.gz
> After INSERT INTO:
> 000000_0.gz
> 000000_0.gz_copy_1
> This causes corrupted output when doing a SELECT * on the table.
> Correct behavior should be to pick a valid filename such as:
> 000000_0_copy_1.gz
