hm. Yeah, your port is good...have you seen this thread: http://stackoverflow.com/questions/27288380/fail-to-use-spark-cassandra-connector ? It seems that you might be running into version mis-match issues?

What versions of Spark/Cassandra-connector are you trying to use?

Sorry my answer I hit terminal lsof -i:9160: result is

so 9160 port is available or not ?

Yes my cassandra is listening on 9160 I think. Actually I know from yaml file. The file includes :

rpc_address: localhost
# port for Thrift to listen for clients on
rpc_port: 9160

I check the port "nc -z localhost 9160; echo $?" it returns me "0". I think it close, should I open this port ?

Is your cassandra installation actually listening on 9160?

I am running an out-of-the box cassandra conf where 

rpc_address: localhost
# port for Thrift to listen for clients on
rpc_port: 9160

Thanks alot Mohammed, Gerard and Yana. 
I can write to table, but exception returns me. It says "Exception in thread "main" java.io.IOException: Failed to open thrift connection to Cassandra at 127.0.0.1:9160"

In yaml file :
rpc_address: localhost
rpc_port: 9160

And at project :

.set("spark.cassandra.connection.host", "127.0.0.1")
.set("spark.cassandra.connection.rpc.port", "9160");

or

.set("spark.cassandra.connection.host", "localhost")
.set("spark.cassandra.connection.rpc.port", "9160");

whatever I write setting,  I get same exception. Any help ??

yes, whatever you put for listen_address in cassandra.yaml. Also, you should try to connect to your cassandra cluster via bin/cqlsh to make sure you have connectivity before you try to make a a connection via spark.

Hi,
I run my project on local. How can find ip address of my cassandra host ? From cassandra.yaml or ??

????? = <ip address of your cassandra host>

Hi ,

How can I find spark.cassandra.connection.host? And what should I change ? Should I change cassandra.yaml ? 

Error says me "Exception in thread "main" java.io.IOException: Failed to open native connection to Cassandra at {127.0.1.1}:9042"

What should I add SparkConf sparkConf = new SparkConf().setAppName("JavaApiDemo").set("spark.driver.allowMultipleContexts", "true").set("spark.cassandra.connection.host", ?????);

Best

Check your spark.cassandra.connection.host setting. It should be pointing to one of your Cassandra nodes.

Hi,

 

I am using cassandraDB in my project. I had that error Exception in thread "main" java.io.IOException: Failed to open native connection to Cassandra at {127.0.1.1}:9042

 

I think I have to modify the submit line. What should I add or remove when I submit my project?

 

Best,

yasemin
