>                 Key: IMPALA-1373
>                 URL: https://issues.apache.org/jira/browse/IMPALA-1373
>             Project: IMPALA
>          Issue Type: Bug
>          Components: Backend
>    Affects Versions: Impala 2.0
>            Reporter: John Russell
>            Priority: Minor
>
> Marking as minor because file writer functionality not part of the 2.0 release.
> Discussed with Ippo, he has a fix ready to go.
> If Impala writes a .snappy file, some extra bytes might get included by mistake:
> {code}
> [localhost:21000] > set compression_codec=snappy;
> [localhost:21000] > set allow_unsupported_formats=1;
> [localhost:21000] > insert into csv_compressed values
> ('one - snappy','two - snappy','three - snappy');
> [localhost:21000] > select * from csv_compressed;
