Subject [jira] Commented: (CHUKWA-495) Implement Pig 0.7.0 compatible Loader and Storer classes
Date Mon, 19 Jul 2010 04:57:50 GMT


Bill Graham commented on CHUKWA-495:

I've tested the loader on my cluster and it's working well. I don't have any use cases where
the storer is used in my cluster though, so I can't easily test that. The pig unit tests pass
though. I still need to update the ChukwaArchiver class as well and then I can submit a patch,
hopefully in the next day or two.

> Pig 0.7.0 introduces a revamped Load/Store model that is not backward compatible with
previous Pig releases. We need to create new classes to handle loading/storing Chukwa data
from Pig. Since the new load/store model uses abstract super classes instead of interfaces,
I propose we deprecate {{org.apache.hadoop.chukwa.ChukwaStorage}} and create the following
> {noformat}
> org.apache.hadoop.chukwa.pig.ChukwaLoader
> org.apache.hadoop.chukwa.pig.ChukwaStorer
> {noformat}
> Note the addition of the pig sub-package. Thoughts about this approach?
