Jonathan Gray updated HBASE-1718:
---------------------------------
Attachment: HBASE-1718-v1.patch
Instantiates a new KeyValue at the end of the while loop, meaning we only
re-instantiate once we've passed forward the KV (we can reuse the times we do
continue).
> Reuse of KeyValue during log replay could cause the wrong data to be used
