'I can't run zookeeper
i am new to the kafka world, i want to start zookeeper then when i type this
bin/zookeeper-server-start.sh config/zookeeper.properties
I got the following error
ERROR Unexpected exception, exiting abnormally (org.apache.zookeeper.server.ZooKeeperServerMain)
java.net.BindException: Address already in use
ERROR Unexpected exception, exiting abnormally (org.apache.zookeeper.server.ZooKeeperServerMain)
java.net.BindException: Address already in use
Then i tried netstat -nlp|grep 2181
but there is no process running
tcp 0 0 0.0.0.0:2181 0.0.0.0:* LISTEN -
Some light please
Solution 1:[1]
For this case, You need to see if zookeeper is running or not
use below command
sudo lsof -i :2181
You will get
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 1005 zookeeper 33u IPv6 17209 0t0 TCP *:2181 (LISTEN)
java 1005 zookeeper 34u IPv6 327225 0t0 TCP localhost:2181->localhost:43566 (ESTABLISHED)
java 22585 root 88u IPv6 324552 0t0 TCP localhost:43566->localhost:2181 (ESTABLISHED)
like statement. Now kill the zookeeper to start again.
sudo kill -9 1005
Then use below to start zookeeper
bin/zookeeper-server-start.sh config/zookeeper.properties
Solution 2:[2]
Sounds like zookeeper server is running.
try:
bin/zkServer.sh stop from the zookeeper directory to shut it down and then:
bin/zookeeper-server-start.sh config/zookeeper.properties
from the kafka directory
That fixed my issue
Solution 3:[3]
There must be some stale process using the port 2181.I had the same issue.First I checked the status of the server:
/usr/share/zookeeper$ bin/zkServer.sh status
or
/usr/share/zookeeper$ echo status | nc 127.0.0.1 2181
Then, I tried to start kafka and it failed with the same error. I changed permission and run as sudo..it didn't work either. Since i couldn't see any process using the port. I restarted my computer and it worked!!.
Solution 4:[4]
Check if zookeeper is already running or not by using this command.
bin/kafka-topics.sh --list --zookeeper localhost:2181
Check if you get number of topics, if you get any that means Zookeeper was already running. So verify whether Zookeeper is already running or not.
Solution 5:[5]
First, stop the Zookeeper with the command below:
$ bin/zookeeper-server-stop.sh config/zookeeper.properties
Then, start it again and you should be good to go:
$ bin/zookeeper-server-start.sh config/zookeeper.properties
Solution 6:[6]
May be another user is running the process. check using jps if any process with Quorum is running kill it and then try
Solution 7:[7]
If you are running command bin/zookeeper-server-start.sh config/zookeeper.properties
and getting error :
ERROR Unexpected exception, exiting abnormally (org.apache.zookeeper.server.ZooKeeperServerMain)
java.net.BindException: Address already in use
at sun.nio.ch.Net.bind0(Native Method)
In that case in your virtual machine port 2181 is already using by zookeeper.
so in kafka zookeeper.properties change the clientPort value to the port which is not in use like 5181
Again run the command and Zookeeper will start working.
Solution 8:[8]
I have solved the problem by doing following commands.
Go to kafka folder where you installed and type
sudo bin/zookeeper-server-stop.shbin/zookeeper-server-start.sh config/zookeeper.properties
I hope this helps. Best of luck!
Solution 9:[9]
Maybe you can stop your hbase first.
just like this follow..
[root@master kafka_2.11-0.10.1.0]# stop-hbase.sh

Solution 10:[10]
I got the same problem. I got it because zookeeper server is crashed by my laptop crash. I got solved by the help from the below link.
How to recover Zookeeper from java.io.EOFException after a server crash?
I found the offending log file by opening one by one [Zookeper-data-dir]/zookeeper_0/version-2. And found a log file without head or any other thing. When I deleted it, I got my problem solved and my zookeeper server started running normally.
Solution 11:[11]
Seems to be the ZooKeeper port 2181 is still in use, Please follow the below steps to address this issue:
Use the netstat command to find the process that is holding onto port 2181. Kill the process that is using the ZooKeeper port 2181:
$ netstat -antp | grep 2181
tcp 0 0 0.0.0.0:2181 0.0.0.0:*
LISTEN 28016/java <defunct>
$ kill -9 28016
Solution 12:[12]
Restarting the kafka process solves the issue.
Solution 13:[13]
There is existing zookeeper running, how should I remove this. And than stop the zookeeper
bin/kafka-topics.sh --list --zookeeper localhost:2181 test
Solution 14:[14]
Many mentioned the process for linux versions.
In case if we want to identify the same for windows, we can identify with below
From PowerShell, finding the port listening to 2181
PS C:\Users\<username>> netstat -ano | findstr 2181
TCP [::1]:2181 [::]:0 LISTENING 4564
Option #1: kill that process id using task kill
PS C:\Users\vishnus> taskkill /F /PID 4564
In case this option doesn't work and failing
ERROR: The process with PID 4564 could not be terminated.
Reason: Access is denied.
Option #2
Go to "Task Manager" --> Services tab, check for PID column and go to that process and right click and mark it as stop. then it will get stopped.
By this time, the earlier instance is killed, so you can start the zookeeper
Solution 15:[15]
I have the same problem and then I debug step by step and find the solution as follows:
stop the zookeeper:
/opt/kafka_2.13-2.7.0/bin/zookeeper-server-stop.shThen I check whether the zookeeper process has indeed been stopped:
ps aux | grep zookeeper
If the zookeeper has been stopped, then no zookeeper process should be displayed. You can also check the zookeeper process via port number or java process. If your port number for zookeeper is the default 2181, you can check which process is listening to this port by runningsudo lsof -i :2181. You can also check the all the java processs and find the corresponding zookeeper process by runningsudo ps -fC javaIf the zookeeper has not been stopped, run
sudo kill -9 zookeeper_process_idto kill it.
After this, we are sure that zookeeper have indeed been stopped. If we run jps, the QuorumPeerMain will not be shown.
After this, we can restart the zookeeper,
/opt/kafka_2.13-2.7.0/bin/zookeeper-server-start.sh /opt/kafka_2.13-2.7.0/config/zookeeper.properties
Solution 16:[16]
I think the problem is in your qs = Post.objects.filter(category = Category.objects.filter(slug = category_slug)) line.
If you want to filter posts by slug you can do this by __in.
qs = Post.objects.filter(category = Category.objects.filter(slug__in = category_slug))
Solution 17:[17]
I've found my answer. if you have the same issue in the qs line write this :
category_slug = self.kwargs.get('slug')
category = Category.objects.get(slug = category_slug)
category_id = Category.objects.get(id = category.id)
qs = Post.objects.filter(category = category_id)
instead of this:
category_slug = self.kwargs.get('slug')
qs = Post.objects.filter(category = Category.objects.filter(slug = category_slug))
