-------------------------------------
Hi!
Actually, this is not a bug, it was made so by design. There's a javadoc note
on that. Also, note that this is used in HBASE-6618 - more advanced
implementation with ranges support (patch is ready, waits for review).
[~maryannxue] Could you please take a look at that one too?
Thank you for looking at the filter and trying to improve it!
> FuzzyRowFilter would have wrong behaviors if user gives an arbitary byte for
> an "unfixed" position instead of byte 0

> An actual case can be:
> we want to match "a?ex", so we give "a?ex" as input of "key bytes", and
> "0100" as input of "meta bytes".
> if we start with row = "\0\0\0\0", the next hint would turn out to be "a?ex"
> while actually the right hint should be "a\0ex".
