Jonathan Ellis commented on CASSANDRA-126:
------------------------------------------

sorry, I was looking at the wrong git repo.  I don't see any exceptions anymore that you'd
want to change, either.

> In SequenceFile.AbstractReader.seekTo(), an IOException is thrown when a key can't be
found in an SSTable. This is incorrect. The BF associated with the SSTable could return a
false positive. So a key may indeed not be present in the SSTable file. We need to handle
this case accordingly.
