Subject [jira] [Commented] (HBASE-10067) Filters are not applied if columns are added to the scanner
Date Thu, 26 Jun 2014 13:27:24 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14044649#comment-14044649

Anoop Sam John commented on HBASE-10067:
----------------------------------------

You have to add the condition column also on to the Scan and if that column value not needed
use SingleColumnValueExcludeFilter instead of SCVF.

> Filters are not applied if columns are added to the scanner

>             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
