> SkipFilter javadoc is incorrect
> -------------------------------
>
> Key: HBASE-6481
> URL: https://issues.apache.org/jira/browse/HBASE-6481
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.94.0
> Reporter: Shrijeet Paliwal
> Priority: Minor
> Labels: newbie
> Fix For: 0.96.0
>
> Attachments: 0001-HBASE-6481-SkipFilter-javadoc-is-incorrect.patch
>
>
> The javadoc for SkipFilter
> (http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/filter/SkipFilter.html)
> states :
>
> A wrapper filter that filters an entire row if any of the KeyValue checks do
> not pass.
>
> But the example same javadocs gives to support this statement is wrong. The
> *scan.setFilter(new SkipFilter(new ValueFilter(CompareOp.EQUAL,
> new BinaryComparator(Bytes.toBytes(0))));* , will only emit rows which
> have all column values zero. In other words it is going to skip all rows for
> which
> ValueFilter(CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(0))) does not
> pass , which happen to be all non zero valued cells.
> In the same example a ValueFilter created with CompareOp.NOT_EQUAL will
> filter out the rows which have a column value zero.
