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.
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.
Please correct me if I am getting this wrong.
