stack commented on HBASE-16074:
-------------------------------
A review of fake keys is probably in order. We have a good variety of fake keys
used in different scenarios. In this case the keys are denoted by their
timestamp being OLDEST_TIMESTAMP and it was just a fluke that we fell through
on a code path that normally weeds the fake keys. I suppose fakekeys could all
carry a marker interface but that'd be one more thing to compare as Cells leave
the server and we already do too many compares. A review is in order for sure.
Would probably rather work on a redo of our merge sort... Thanks [~anoop.hbase]
