Upgrading to ES Version 2.2.0 issue

im upgrading my java client from es version 0.20.6 to 2.2.0. since some classes were deprecated i modify my code to work with latest version. i dnt have any compiler issues but now im having runtime issue which i couldnt solve yet. please tell me how solve this issue.

this is the code
Settings settings = Settings.settingsBuilder().put(CLUSTER_NAME_PARAM, clusterName).put(CLIENT_TRANSPORT_SNIFF_PARAM, true).build();

from below code im getting this error. (ElasticSearchDAOImpl.java:135 is below code line)
client = new TransportClient.Builder().settings(settings).build();
