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.
