Vasu Mariyala commented on HBASE-10067:
---------------------------------------
Only when the filter columns are part of the scan column list, the filter is
applied. See HBASE-4364 for more information.
> Filters are not applied if columns are added to the scanner

> Key: HBASE-10067
> URL: https://issues.apache.org/jira/browse/HBASE-10067
> Project: HBase
> Issue Type: Bug
> Components: Coprocessors, Filters, Scanners
> Affects Versions: 0.94.6
> Environment: Linux 2.6.32-279.11.1.el6.x86_64
> Reporter: Vikram Singh Chandel
>
> While applying columns to scanner the filtering does not happen and entire
> scan of the table is done
> Expected behaviour: Filters should be applied when particular columns are
> added to scanner
> Actual behaviour: Filter are not applied entire result set is returned
> Code Snippet:
> Scan scan = new Scan();
> scan.addColumn(family, qualifier);//Entire scan happens Filters are
> ignored
> SingleColumnValueFilter filterOne =new SingleColumnValueFilter(colFal,col,
> CompareOp.EQUAL, val);
> filterOne.setFilterIfMissing(true);
>
> FilterList filter = new FilterList(Operator.MUST_PASS_ALL,
> Arrays.asList((Filter) filterOne));
> scan.setFilter(filter); // Not working
> If addFamily is used it works
> scan.addFamily(family);
> scan.setFilter(filter); //Works
