Erik Holstad commented on HBASE-1619:
-------------------------------------

@JGray, haha, yeah I think so.

@Stack, I'm going to file a couple of issues during this week related to Cascading and have
no problem moving them out of 0.20 if everything else is done. But don't think that they are
going to big and complicated and take a lot of time to fix.

> While working on the HBase tap and scheme for Cascading I came across a situation where
you want to add a bunch of KeyValues to a Put object.
> Looking at the code for putting KeyValues in put we copy the family from the KeyValue
and use that as a key. So I was thinking that it might be a good idea to just "point"
> into the KV by using a ImmutableBytesWritable and use that as the key instead. This is
going to be good when working with MR jobs.
