Subject Scanner exceptions in .20
Date Fri, 26 Jun 2009 19:25:57 GMT

Hey,

I'm doing the following to get a scanner on a tall table: 

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