get rid of scanner timeout
--------------------------

                 Key: HBASE-2161
                 URL: https://issues.apache.org/jira/browse/HBASE-2161
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: ryan rawson
             Fix For: 0.21.0


the client side code has this in ClientScanner.next():

            if (e instanceof UnknownScannerException &&
                lastNext + scannerTimeout < System.currentTimeMillis()) {
              ScannerTimeoutException ex = new ScannerTimeoutException();
              ex.initCause(e);
              throw ex;
            }

This will cause the client-side to timeout after the 'scannerTimeout'. There doesn't seem to be any good reason for this - we can just restart the scanner at the last row.  Leave the server-side scanner as is, but clients should be able to have a 5 day scan that is continuously being restarted.
