stack updated HBASE-7289:
-------------------------
Release Note:
Strips Writable from KeyValue. Side effect has us protobuf'ing KeyValue when
we put it into a Result so this should SLOW HBase considerably until we address
KeyValue serialization over in HBASE-7233.
HBASE-7215 added MapReduce serializers for Result, Put, Delete, etc. This
issue adds a serializer for KeyValue. If using HFileOutputFormat, be sure to
add the serializer to your configuration: for example:
{code}
Job job = new Job(conf, "YOUR_MAPREDUCE_JOB");
job.getConfiguration().setStrings("io.serializations",
conf.get("io.serializations"),
MutationSerialization.class.getName(),
ResultSerialization.class.getName(),
KeyValueSerialization.class.getName());
{code}

> Made new issue to strip Writable from KeyValue. It used to be HBASE-7233 but
> I morphed my own issue discussion of how to serialize KVs.
> This issue is about removing Writable from KV and making baseline protobufing
> work over mapreduce and rpc.
