--------------------------------
Attachment: HBASE-6618_2.path
Fixed typo, now filter tests should pass. Not sure about why metrics tests failed. Will look at it if occur again

> Apart from current ability to specify fuzzy row filter e.g. for <userId_actionId> format as ????_0004 (where 0004 - actionId) it would be great to also have ability to specify the "fuzzy range" , e.g. ????_0004, ..., ????_0099.
> See initial discussion here: http://search-hadoop.com/m/WVLJdX0Z65
> Note: currently it is possible to provide multiple fuzzy row rules to existing FuzzyRowFilter, but in case when the range is big (contains thousands of values) it is not efficient.
> Filter should perform efficient fast-forwarding during the scan (this is what distinguishes it from regex row filter).
> While such functionality may seem like a proper fit for custom filter (i.e. not including into standard filter set) it looks like the filter may be very re-useable. We may judge based on the implementation that will hopefully be added.
