Shrijeet Paliwal created HBASE-6481:
---------------------------------------
Summary: 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
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.
