Subject [jira] Updated: (HBASE-1821) Filtering by SingleColumnValueFilter bug
Date Thu, 10 Sep 2009 15:53:57 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1821?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Olariu Adrian updated HBASE-1821:
---------------------------------

    Attachment: HBASE-1821.patch

Problem description:
        Filter filter1 = new SingleColumnValueFilter(Bytes.toBytes("F1"), Bytes.toBytes("c1"),
CompareOp.EQUAL, Bytes.toBytes("1"));
        Filter filter2 = new SingleColumnValueFilter(Bytes.toBytes("F1"), Bytes.toBytes("c2"),
CompareOp.EQUAL, Bytes.toBytes("1"));
        List<Filter> rowFilters = new ArrayList<Filter>();
        rowFilters.add(filter1);rowFilters.add(filter2);
        Filter filter = new FilterList(FilterList.Operator.MUST_PASS_ALL, rowFilters);

        s.addColumn(Bytes.toBytes("F1"), Bytes.toBytes("c1"));
        s.addColumn(Bytes.toBytes("F1"), Bytes.toBytes("c2"));
        s.setFilter(filter);

This scan returns all rows the contains F1:c1 whit val "1" or contains F1:c2 whit val "1"
or contains both. It should return only the rows that match both: filter1 and filter2.


Solution:
if the filter noesn't find inside a row a Column-Value match than the FilterRow method should
return true.


Patch attached.
