dyno_scan goes into infinite loop

[balajivenki]

When using dyno_scan to find keys with pattern the call goes into infinite loop and never finishes. The condition for isComplete never seem to return true because cursor value is never 0 after it scrolls.

com.netflix.dyno.jedis.CursorBasedResultImpl#isComplete

Here is the sample code I used to test the same

` System.out.println("SCAN TEST -- begin");
String keyPattern = "SetKey-41*";

    System.out.println("Reading keys  with pattern " + keyPattern);
    CursorBasedResult<String> cbi = null;

    Set<String> resultKeys = Sets.newHashSet();
    int count = 0;
    do {
        try {

            cbi = dynoJedisClient.dyno_scan(cbi, 50, keyPattern);
        } catch (PoolOfflineException ex) {
            System.out.println("Caught exception.... retrying scan");
            cbi = null;
            continue;
        }


        List<String> results = cbi.getResult();
        count += results.size();
        for (String res : results) {
            resultKeys.add(res);
        }
        System.out.println("Count: " + count);
    } while ((cbi == null) || !cbi.isComplete());`
