i creating cluster using below code 

poolingoptions poolingoptions = new poolingoptions();         poolingoptions.setcoreconnectionsperhost(hostdistance.local, 52)         .setmaxconnectionsperhost(hostdistance.local, 80)         .setmaxrequestsperconnection(hostdistance.local, 500);      socketoptions socketoption = new socketoptions();     socketoption.setreadtimeoutmillis(600000)     .setreceivebuffersize(1024*512)     .setsendbuffersize(1024*512)     .setkeepalive(true).setconnecttimeoutmillis(1800000);      cluster = cluster.builder()             .addcontactpoints(cassandrahosts.get("host_1"), cassandrahosts.get("host_2"))             .withpoolingoptions(poolingoptions)             .withport(cassandraport)             .withsocketoptions(socketoption)             .withloadbalancingpolicy(new tokenawarepolicy(new dcawareroundrobinpolicy())).build();     session session = cluster.connect(cassandradb);
  • cassandra version: 2.2.1
  • java 7
  • is there other way execute select query without read time out exception
