Mike Hurley commented on AVRO-1862:
-----------------------------------
Is this really that useful? For instance, with zip files I would never name a
file ".stored.zip" or ".deflate.zip". Some people use names like ".h264.mp4"
for videos, but that seems kind of rare. I guess it really doesn't hurt since
it's a new feature that somebody explicitly has to opt-in to use.
> AvroOutputFormat saves compressed avrò files without respecting codec's

> Issue Type: Improvement
> Components: java

>
> Common pattern in naming compressed files is giving them extension derived
> from compression codec, for example: {{.gz}}, {{.zip}}, {{.bz2}}.
> {{AvroOutputFormat}} currently does not respect this convention.
> I've adapted some code from Hadoop's {{TextOutputFormat}} in
> backward-compatible manner adding following {{JobConf}} property:
> {{avro.mapred.output.extension.from-codec}} ({{boolean}}, default: {{false}})
> - when set to {{true}}, extension will be changed according to above rule.
> EDIT: Please take a look at first comment for an update. {{.gz.avro}},
> {{.snappy.avro}} will be an extension of the file when above property will be
> set to true.
