Subject Re: Scanner exceptions in .20
Date Fri, 26 Jun 2009 19:35:35 GMT

This exception does not happen if I remove the addColumn, and leave only
addFamily (linkScan.addFamily(Bytes.toBytes("type")) .

also, forgot I also have start and stop rows set:



 Scan linkScan = new Scan();.
 linkScan.addColumn(Bytes.toBytes("type"), Bytes.toBytes("ELECTRONICS"));
            linkScan.setStartRow (Bytes.toBytes(e + "|"));
            linkScan.setStopRow (Bytes.toBytes(e + " "));
 ResultScanner scanner = tblEntity.getScanner(linkScan);
 for (Result linkRowResult : scanner ) {
    String row = Bytes.toString(linkRowResult.getRow());   
 }
