Subject [jira] Updated: (HBASE-1626) Allow emitting Deletes out of new TableReducer
Date Wed, 08 Jul 2009 14:19:14 GMT

Lars George updated HBASE-1626:

    Attachment: 1626.patch

Patch 1626.patch combines the fix to IdentityTableReduce and applies the changes Stack did
to allow for Put's and Delete's to be passed to the TOF. I kept the key type as is but only
changed the value. That way the change is less intrusive - it is to be discussed if that is
what we want or not. We could still decide to do away with TableReducer - but the TableMapper
would stay so the change would be introducing a slight imbalance.

As far as not enforcing the value type but now use a generic Writable - well I think that
is OK given an exception is thrown if someone really stuffs that up. While we do not have
a base class for Put and Delete we have to go down this route.
