David Ciemiewicz commented on PIG-42:
-------------------------------------
Hadoop Archives are not really the solution here. I want my code to with
exactly the same file name references whether I have 100 gzip compressed (or
bzip2 compressed) part files or a single concatenation of the individually
compressed part files.
I have to change all my filename references to use a har.
What we really want are simple concatenations of gzip files and bzip2 files
that work with map reduce.
> Pig should be able to split Gzip files like it can split Bzip files

> It would be nice to be able to split gzip files like we can split bzip files.
> Unfortunately, we don't have a sync point for the split in the gzip format.
> Gzip file format supports the notion of concatenate gzipped files. When
> gzipped files are concatenated together they are treated as a single file. So
> to make a gzipped file splittable we can used an empty compressed file with
> some salt in the headers as a sync signature. Then we can make the gzip file
> splittable by using this sync signature between compressed segments of the
> file.
