-------------------------------------

             Summary: 0.94 filterRow() may be skipped in 0.96(or onwards) code
                 Key: HBASE-10366
                 URL: https://issues.apache.org/jira/browse/HBASE-10366
             Project: HBase
          Issue Type: Bug
          Components: Filters
            Reporter: Jeffrey Zhong
            Assignee: Jeffrey Zhong
            Priority: Critical
             Fix For: 0.98.0, 0.96.2


HBASE-6429 combines both filterRow & filterRow(List<KeyValue> kvs) functions in Filter. 
While 0.94 code or older, it may not implement hasFilterRow as HBase-6429 expected because hasFilterRow only returns true when filterRow(List<KeyValue> kvs) is overridden not the filterRow(). Therefore, the filterRow() will be skipped.

Since we don't ask 0.94 users to update their existing filter code, the issue will cause scan returns unexpected keyvalues and break the backward compatibility.
