Re: Zookeeper not starting

[Mich Talebzadeh]

Have you looked at the zookeeper log to see why it is failing to start?

On the zookeeper host do

ps -ef | grep zookeeper | grep zookeeper.log.dir --color
Says something like below

hduser   26214 1  0 23:18 pts/200:00:01 /opt/jdk1.8.0_201/bin/java
-Dzookeeper.log.dir=/home/hduser/hadoop-3.1.1/logs
-Dzookeeper.log.file=zookeeper-hduser-server-rhes75.log

Go to that directory and look at the log file(example here ->
/home/hduser/hadoop-3.1.1/logs/zookeeper-hduser-server-rhes75.log

To find out the cause of error

Re: Zookeeper not starting

[Lemi Odidi]

Hello Mich,
Thank you for your response. I have 3 instances running Kafka in this
environment. All these instances had zookeepers running on them
independently until the one in question stopped running.
The version of kafka is kafka_2.12-1.1.0.jar.asc.

Thanks for help.
Regards, Lemi

Hi Lemi,

How many ZooKeepers do you have in your topology?

Also ZooKeeper and Kafka versions.

If it says Kafka is running there must be ZooKeeper somewhere already

Lemi,

You screenshots are not passing through the distribution list.

Would you be able to paste the text from the terminal into your message?
