Description

e.g.

startRow : "112"

rowPrefixFilter : "11"

The Result of this scan might contains : "111", which unexpected.

  public Scan setRowPrefixFilter(byte[] rowPrefix) {
    if (rowPrefix == null) {
      setStartRow(HConstants.EMPTY_START_ROW);
      setStopRow(HConstants.EMPTY_END_ROW);
    } else {
      this.setStartRow(rowPrefix);
      this.setStopRow(calculateTheClosestNextRowKeyForPrefix(rowPrefix));
    }
    return this;
  }

 Scan#setRowPrefixFilter achieves this function by setting startRow and stopRow, ignoring the situation that startRow may have been set.
