Lars Hofhansl updated HBASE-8388:
---------------------------------
Attachment: 8388-trunk-v3.txt
This one passes the three tests that failed before.
It gets rid of useRowColBloom in StoreScanner and always tried to use a BF when
there is one (ROW or ROWCOL).
Also it makes the KV handling for the BF optimization explicit in SQM (before
the fake KVs were implicitly filtered because of the time range/isDone checks).
This is by no means ready for commit, I am still reading the code and debugging
a bit more to fully understand how things interact.
