Nick Dimiduk updated HBASE-12222:
---------------------------------
Description:
FuzzyRowFilter getNextCellHint doesn't take into account jagged rowkeys and
produces surprising results. For example, given a table of
{noformat}
0
0/0
0/1
0/2
1
1/0
1/1
1/2
2
2/0
2/1
2/2
{noformat}
and FuzzyPrefixFilter like "?/2", {1, 0, 0}
I would expect
{noformat}
0/2
1/2
2/2
{noformat}
The results include the rows '0', '1', and '2'
was:
FuzzyRowFilter getNextCellHint doesn't take into account jagged rowkeys, thus
it will skip too far ahead. For example, given a table of
{noformat}
0
