Subject [jira] Created: (HBASE-1647) Filter#filterRow is called too often, filters rows it shouldn't have

Filter#filterRow is called too often, filters rows it shouldn't have
--------------------------------------------------------------------

                 Key: HBASE-1647
                 URL: https://issues.apache.org/jira/browse/HBASE-1647
             Project: Hadoop HBase
          Issue Type: Bug
    Affects Versions: 0.20.0
            Reporter: Doğacan Güney


Filter#filterRow is called from ScanQueryMatcher#filterEntireRow which is called from StoreScanner.next.
However, if I understood the code correctly, StoreScanner processes KeyValue-s in a column-oriented
order (i.e. after row1-col1 comes row2-col1, not row1-col2). Thus, when filterEntireRow is
called, in reality, the filter only processed (via filterKeyValue) only one column of a row.
