Kafka Zookeeper - Java.net.BindException: Address already in use

I have Kafka setup on my machine and was running fine.

I then installed NetBeans and I think that messed things up. Now my zookeeper is not starting.

After netBeans installation I faced an error while running it

The JDK is missing and is required to run some netbeans modules

I solved the issue using this post

Now when I start zookeeper using:

sudo bin/zookeeper-server-start.sh config/zookeeper.properties

I get the following traceback:

I have tried this:

netstat -ant | grep :2181

Gives me the following output:

tcp6       0      0 :::2181                 :::*                    LISTEN

Before installing NetBeans the output was:

tcp6       0      0 :::2181                 :::*                    LISTEN

I think this is the issue, but I don't know how to resolve this.

I have tried sudo lsof -i :2181

Output:

Some process seems to use the port. Try the command lsof -i :2181 to see what process it is. – Shivers
I have updated the post – Blissful
it looks like something is using port 2181. It's process ID (PID) is 1005. Send a kill signal to that process with kill -9 1005, maybe sudo kill -9 1005 – Haberdashery
@DmitryMinkovsky I have tried doing that but its still giving the same traceback – Blissful
Should I uninstall netBeans? – Blissful

Go to Kafka folder where you installed and type following command : 

sudo bin/zookeeper-server-stop.sh

Then try to execute the following command : 

bin/zookeeper-server-start.sh config/zookeeper.properties

Hope you will get rid off from your Error.

You should go to the config folder. Then there is a file zookeeper.properties open the file and set clientPort=5181(if it is unused port) and set maxClientCnxns=5 (initially here was 0 instead of 5, you can set it as your requirement).
