> 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
classes:
> {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?
