I am also running into this problem. I= have already enabled start_native_transport: true

And = by this, I am trying to make a connection-

=A0=A0=A0 private Cassand= raDatastaxConnection() {

=A0=A0=A0 =A0=A0=A0 try{
=A0=A0=A0 =A0=A0=A0 =A0=A0=A0 cluster =3D C= luster.builder().addContactPoint("localhost").build();
=A0=A0= =A0 =A0=A0=A0 =A0=A0=A0 session =3D cluster.connect("my_keyspace"= );=A0=A0=A0 =A0=A0=A0 =A0=A0=A0
=A0=A0=A0 =A0=A0=A0 } catch (NoHostAvai= lableException e) {
=A0=A0=A0 =A0=A0=A0 =A0=A0=A0 throw new RuntimeException(e);
=A0=A0=A0 = =A0=A0=A0 }
=A0=A0=A0 }

And everytime it gives me the same = exception-

com.datastax.driver= .core.exceptions.NoHostAvailableException: All host(s) tried for query fail= ed (tried: [localhost/127.0.0.1])

Any idea how to fix this problem?

Thanks for the hel= p.

Then tried a sample program to connect to the cluster

=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 .withPort(9160)
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 .build();

But sadly its=A0returning=A0com.datastax.driver.core.exceptions.NoH= ostAvailableException: All host(s) tried for query failed=A0=A0=A0

I am using cassandra 1.2.2

Can any one suggest me whats wrong with that.=A0

And i am really sorry for posting =A0datastax java driver related ques= tion in this forum, can't find a better place for the instant reaction= =A0
