----------------------------
Assignee: (was: Harsh J)
> Pig doesn't detect all forms of compression extensions properly
> ---------------------------------------------------------------
>
> Key: PIG-2746
> URL: https://issues.apache.org/jira/browse/PIG-2746
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.8.1
> Reporter: Harsh J
> Attachments: PIG-2746.patch, PIG-2746.patch, PIG-2746.patch,

> The PigStorage has the following snippet.
> {code}
> private void setCompression(Path path, Job job) {
> String location=path.getName();
> if (location.endsWith(".bz2") || location.endsWith(".bz")) {
> FileOutputFormat.setCompressOutput(job, true);
> FileOutputFormat.setOutputCompressorClass(job, BZip2Codec.class);
> } else if (location.endsWith(".gz")) {
> FileOutputFormat.setCompressOutput(job, true);
> FileOutputFormat.setOutputCompressorClass(job, GzipCodec.class);
> } else {
> FileOutputFormat.setCompressOutput( job, false);
> }
> }
> {code}
> This limits it to only work with STORE filenames provided as 'output.gz' or
> 'output.bz2' and for the rest (like LZO) one has to specify codecs and
> manually enable compression.
> Ideally Pig can rely on Hadoop's extension-to-codec detector instead of
> having this ladder.
