Todd Lipcon commented on HADOOP-7350:
-------------------------------------
bq. This doesn't need to be updated
Sorry, the default doesn't need to change, but the docs should be updated: it
no longer needs to be one of the codecs listed in io.compression.codecs. It
just needs to be any codec that's "registered" (either via conf or via
ServiceLoader). I don't know the best verbiage to succinctly document it,
though.
The rest of your points make sense.

> By using a ServiceLoader users wouldn't have to add codec classes to
> io.compression.codecs for codecs that aren't shipped with Hadoop (e.g. LZO),
> since they would be automatically picked up from the classpath.
