Julian Zhou commented on HBASE-9747: ------------------------------------ Is this kinds of logic? --> In the for loop of FilterList#filterRowKey, there are 2 filters in this case: PrefixFilter and SingleColumnValueFilter. The 1st row 'a1','f1:q2','111' was filtered by PrefixFilter, but was passed (survived) via the 2nd filter SingleColumnValueFilter, since SingleColumnValueFilter is actually not a rowkey filter but a row/kv filter, but it inherits from FilterBase#filterAllRemaining() and FilterBase#filterRowKey's returning "false" value, which is not expected in this case. Sounds like we need to deny the "non-rowkey filter" in the rowkey filter execution path to avoid the filtered row survived? > PrefixFilter with OR condition gives wrong results > -------------------------------------------------- > > Key: HBASE-9747 > URL: https://issues.apache.org/jira/browse/HBASE-9747 > Project: HBase > Issue Type: Bug > Components: Filters > Affects Versions: 0.94.9 > Reporter: Deepa Remesh > > 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 -- This message was sent by Atlassian JIRA (v6.1#6144)
