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

             Summary: ORDER BY with a null column miss some data.
                 Key: TAJO-904
                 URL: https://issues.apache.org/jira/browse/TAJO-904
             Project: Tajo
          Issue Type: Bug
            Reporter: Hyoungjun Kim
            Assignee: Hyoungjun Kim
            Priority: Trivial


ORDER BY with a null column miss some data. I found RowStoreEncoder has a bug dealing with NULL values. 
"continue" statement should be add.
{code}
      Column col;
      for (int i = 0; i < schema.size(); i++) {
        if (tuple.isNull(i)) {
          nullFlags.set(i);
          continue;
        }
        col = schema.getColumn(i);
{code}
