Cassandra Start up

I am new to the Cassandra database. I have downloaded Cassandra and set the JAVA_HOME. When I try to run, the following exception is thrown:

Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 7199; nested exception is:
java.net.BindException: Address already in use: JVM_Bind.

Can anyone assist me with this issue?

Port 7199 is the default Cassandra's JMX port( used for monitoring). In case you are trying to run multiple instances on one physical machine, modify $CASSANDRA_HOME/conf/cassandra-env.sh configuration file and set different port, for example 7299

JMX_PORT="7299"

I am writing the same but for windows developer command prompt : Let say its showing issue with 9042 port

netstat -ano | findstr : 9042

List all the process using port 9042

taskkill /PID 237979 /F

here 237979 is the processid which is using port 9042

  1. ps -ax | grep cassandra, take note of the process id

  2. kill <pid>

  3. sudo ./cassandra

For those who are facing the same problem using Ubuntu OS a solution can be to kill CassandraDaemon :

pkill -f CassandraDaemon

When you launch for the first time the command "cassandra -f" background daemon is running so Ctrl^C doesn't stop the process.

You could check if cassandra is running by checking the port 

lsof -i :9160

if you got a result back that means it is running

If you want to kill it , do kill -9 "then the pid you got from the last step"

if you want to see the ongoing log run

cassandra -f when you start cassandra

Download the TCPView from http://technet.microsoft.com/en-us/sysinternals/bb897437

Open the TCPView application and sort the output by Port

Click on the record which points to Port - 7199

Right click and "End Process"

Now, run the Cassandra.bat and it should work.

I appears that Cassandra is already running in the background. Try connecting using cassandra-cli.
