----------------------------------

             Summary: FuzzyRowFilter would have wrong behaviors if user gives 
an arbitary byte for an "unfixed" position instead of byte 0
                 Key: HBASE-7892
                 URL: https://issues.apache.org/jira/browse/HBASE-7892
             Project: HBase
          Issue Type: Improvement
          Components: Filters
    Affects Versions: 0.94.5, 0.96.0
            Reporter: Maryann Xue
            Assignee: Maryann Xue
            Priority: Minor


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".
