List of reseek() Examples

Examples of reseek()

org.apache.hadoop.hbase.regionserver.RegionScanner.reseek()
Do a reseek to the required row. Should not be used to seek to a key which may come before the current position. Always seeks to the beginning of a row boundary. @throws IOException @throws IllegalArgumentException if row is null

Examples of org.apache.hadoop.hbase.regionserver.RegionScanner.reseek()

    // set a start row
    s.setStartRow(ROWS_FOUR[1]);
    RegionScanner scanner = region.getScanner(s);


    // reseek to row three.
    scanner.reseek(ROWS_THREE[1]);
    List<KeyValue> results = new ArrayList<KeyValue>();


    // the results should belong to ROWS_THREE[1]
    scanner.next(results);
    for (KeyValue keyValue : results) {
