Fail to connect to single node local cluster with java driver 2.1.0/2.0.5

[Joel Costigliola]

Hi,

Following the getting started steps, I'm trying to setup a single node cassandra cluster on my local machine and connect to it with the java driver.

I'm using the following code inspired by http://www.datastax.com/documentation/developer/java-driver/2.0/java-driver/quick_start/qsSimpleClientCreate_t.html.

public static void main(String[] args) {
    Cluster cluster = Cluster.builder().addContactPoint("127.0.0.1").build();
    Metadata metadata = cluster.getMetadata();
    System.out.printf("Connected to cluster: %s\n", metadata.getClusterName());
    cluster.close();
}

server version : 2.0.10
java driver version : 2.1.0 (also tried with 2.0.5)

Error is:

Exception in thread "main" com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /127.0.0.1:9042 (com.datastax.driver.core.TransportException: [/127.0.0.1:9042] Connection has been closed))
    at com.datastax.driver.core.ControlConnection.reconnectInternal(ControlConnection.java:195)
    at com.datastax.driver.core.ControlConnection.connect(ControlConnection.java:79)
    at com.datastax.driver.core.Cluster$Manager.init(Cluster.java:1143)
    at com.datastax.driver.core.Cluster.getMetadata(Cluster.java:313)

Comments :

• I'm able to connect to cassandra using cqlsh.
• As I'm using the latest stable version of Cassandra and the java driver, I'm expecting them to be compatible.
• port 9042 is open, running telnet 127.0.0.1 9042 gives :
  Trying 127.0.0.1...
  Connected to 127.0.0.1.

What am I doing wrong ?
It is probably a stupid mistake of mine but I can't find it, this is quite frustrating.

Thanks for your help.

Hey .. 

Try localhost instead of 127.0.0.1

Same error when using addContactPoint("localhost").
listen_address and rpc_address are both set to localhost in cassandra configuration

BTW, I'm running on Ubuntu 14.04

Thanks for your response Neha

[Neha Trivedi]

1. you can try removing addContactPoint completely.
Cluster cluster = Cluster.builder().build();


2. Check if ur cassandra is running properly (ps -aux | grep cassandra)?

3. when u start cassandra check from log (/var/log/cassandra/..) do a tail and check which port it is listening to..

[Joel Costigliola]

Ok I found the problem, I was running the code from a project using a lot of third parties libraries and one of them is causing the error (I don't know which one yet).

Running from a "clean" project works perfectly.

Neha, thanks for your time. Appreciated.

Hi,

I am quite new to Cassandra. I am trying to run a piece of code connecting to Cassandra database through Java driver from a Windows system. Here is my piece of code.

public static void main(String[] args) {

Cluster cluster = Cluster.builder().addContactPoint("localhost").build();

Session session = cluster.connect("people");

...

}

I am still getting the error "Exception in thread "main" com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: localhost/127.0.0.1:9042 (com.datastax.driver.core.ConnectionException: [localhost/127.0.0.1:9042] Unexpected error during transport initialization (com.datastax.driver.core.TransportException: [localhost/127.0.0.1:9042] Unexpected exception triggered (java.lang.IndexOutOfBoundsException: Not enough readable bytes - Need 4, maximum is 0))))".

Could you please help me out.

Thanks.

[Kant Kodali]

Make sure Cassandra is running on default port 9042 (not sure what the command would be in windows to check if a process in running on a certain port).

I don't see anything wrong with this piece of code (assuming you have a mapping between localhost and 127.0.0.1)

public static void main(String[] args) {

Cluster cluster = Cluster.builder().addContactPoint("localhost").build();

Session session = cluster.connect("people");

...

}

Cassandra is running on 9042 port and the cluster address is 127.0.0.1 as shown by CQLSH.

[Kevin Gallardo]

Hello, 

That error ("Unexpected error during transport initialization (com.datastax.driver.core.TransportException: [localhost/127.0.0.1:9042] Unexpected exception triggered (java.lang.IndexOutOfBoundsException: Not enough readable bytes - Need 4, maximum is 0))))") seems to indicate an incompatibility between the Cassandra version and the driver's version. More specifically if CQLSH works, since it is packaged with your Cassandra install, so versions of CQLSH and C* are the same, but the driver may not be compatible.

However, I am not sure how much of Cassandra < 3.0 is working well on Windows. You might want to upgrade to the latest version of Cassandra which is 3.5, and the latest Java driver, 3.0.1, since Cassandra is officially supported on Windows since version 3.0.

As a reminder here is the compatibility matrix of DataStax drivers and Cassandra http://docs.datastax.com/en/developer/driver-matrix/doc/common/driverMatrix.html?scroll=driverMatrix__java-driver-matrix.

Cheers.

Hi,

I tried the same by changing the driver version. I got the result.

Thanks a ton, Kevin!!!

sir,i am a student.last year i made a mini project on cassandra but now when i am trying to run it with cassandra it is showing the same error as yours can you plz guide me as to how you resolved the issue.my front end is in java and i am working on linux platform.
