Jonathan Gray resolved HBASE-1718.
----------------------------------
Resolution: Fixed
Hadoop Flags: [Reviewed]
Committed. Upon further thought, this _could_ create cross-family scenario
we've seen in HBASE-1638 / HBASE-1715 (but apurtell says no replay). It does,
however, seem to be the case that this bug completely broke log replay as you
would always end up only having the last seen KV.
> Reuse of KeyValue during log replay could cause the wrong data to be used

> Our meta table got a row key of METAROW in it. Hard to explain how it
> happened, but under code inspection stack found that we are reusing the same
> KV instance for each replayed key.
