Micah Whitacre commented on CRUNCH-246:
---------------------------------------
The mapreduce snapshotting bug in HBase is here[1].
Perhaps I'm incorrectly assuming Chao's use case but I would assume he
targeting processing based on the output of CRUNCH-212 and not necessarily
active data in HBase. Your concerns seems like they are only relevant if you
are trying to hit active HBase data.
