Subject [jira] Created: (HBASE-1190) TableInputFormatBase with row filters scan too far
Date Sun, 08 Feb 2009 01:52:59 GMT
TableInputFormatBase with row filters scan too far 

                 Key: HBASE-1190
                 URL: https://issues.apache.org/jira/browse/HBASE-1190
             Project: Hadoop HBase
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.19.0
            Reporter: Dave Latham
            Priority: Minor

When TableInputFormatBase has a non-null RowFilterInterface to apply, it creates combines
the row filter with a StopRowFilter to get a scanner for each input split.  However, the StopRowFilter
never indicates that fitlerAllRemaining is true, so each input split will end up scanning
to the end of the table.  (Contrast with HTable.getScanner(byte[][] columns, byte[] starRow,
byte[] stopRow, long timestamp) which uses a StopRowFilter wrapped in a WhileMatchRowFilter
to ensure that scanning ends at the stop row.
