> PrefixFilter when used with a SingleColumnValueFilter with an OR condition
> gives wrong results. In below example, each filter when evaluated separately
> gives 1 row each. The OR condition with the two filters gives 3 rows instead
> of 2. Repro below:
> create 't1', 'f1'
> put 't1','a1','f1:q2','111'
> put 't1','b1','f1:q1','112'
> put 't1','c1','f1:q1','113'
> hbase(main):020:0> scan 't1', {FILTER => "PrefixFilter ('b') OR
> SingleColumnValueFilter('f1', 'q1', =, 'binary:113')"}
> ROW COLUMN+CELL
> a1 column=f1:q2,
> timestamp=1381468905492, value=111
> b1 column=f1:q1,
> timestamp=1381468905518, value=112
> c1 column=f1:q1,
> timestamp=1381468905549, value=113
> 3 row(s) in 0.1020 seconds
> hbase(main):021:0> scan 't1', {FILTER => "PrefixFilter ('b')"}
> ROW COLUMN+CELL
> b1 column=f1:q1,
> timestamp=1381468905518, value=112
> 1 row(s) in 0.0150 seconds
> hbase(main):002:0> scan 't1', {FILTER => "SingleColumnValueFilter('f1', 'q1',
> =, 'binary:113')"}
> ROW COLUMN+CELL
> c1 column=f1:q1,
> timestamp=1381469178679, value=113
> 1 row(s) in 0.0140 seconds
