How can I stop ZooKeeper on Ubuntu?

Question

I have installed zookeeperd on Ubuntu 14.04 (Trusty Tahr) as suggested here:

Unfortunately this process is somehow not stoppable. I tried even kill -9

user@node1:/opt/zookeeper-3.4.6$ ps -ef | grep zookeeper
zookeep+  4008     1  8 01:07 ?        00:00:00 /usr/bin/java -cp /etc/zookeeper/conf:/usr/share/java/jline.jar:/usr/share/java/log4j-1.2.jar:/usr/share/java/xercesImpl.jar:/usr/share/java/xmlParserAPIs.jar:/usr/share/java/netty.jar:/usr/share/java/slf4j-api.jar:/usr/share/java/slf4j-log4j12.jar:/usr/share/java/zookeeper.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false -Dzookeeper.log.dir=/var/log/zookeeper -Dzookeeper.root.logger=INFO,ROLLINGFILE org.apache.zookeeper.server.quorum.QuorumPeerMain /etc/zookeeper/conf/zoo.cfg

show process

user      4055  2823  0 01:07 pts/3    00:00:00 grep --color=auto zookeeper

kill it

user@node1:/opt/zookeeper-3.4.6$ sudo kill -9 4008

Check:

user@node1:/opt/zookeeper-3.4.6$ ps -ef | grep zookeeper
zookeep+  4075     1 24 01:07 ?        00:00:00 /usr/bin/java -cp /etc/zookeeper/conf:/usr/share/java/jline.jar:/usr/share/java/log4j-1.2.jar:/usr/share/java/xercesImpl.jar:/usr/share/java/xmlParserAPIs.jar:/usr/share/java/netty.jar:/usr/share/java/slf4j-api.jar:/usr/share/java/slf4j-log4j12.jar:/usr/share/java/zookeeper.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false -Dzookeeper.log.dir=/var/log/zookeeper -Dzookeeper.root.logger=INFO,ROLLINGFILE org.apache.zookeeper.server.quorum.QuorumPeerMain /etc/zookeeper/conf/zoo.cfg

Try script

user@node1:/opt/zookeeper-3.4.6$ sudo /etc/init.d/zookeeper stop
user@node1:/opt/zookeeper-3.4.6$ ps -ef | grep zookeeper
zookeep+  4075     1 29 01:07 ?        00:00:04 /usr/bin/java -cp /etc/zookeeper/conf:/usr/share/java/jline.jar:/usr/share/java/log4j-1.2.jar:/usr/share/java/xercesImpl.jar:/usr/share/java/xmlParserAPIs.jar:/usr/share/java/netty.jar:/usr/share/java/slf4j-api.jar:/usr/share/java/slf4j-log4j12.jar:/usr/share/java/zookeeper.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false -Dzookeeper.log.dir=/var/log/zookeeper -Dzookeeper.root.logger=INFO,ROLLINGFILE org.apache.zookeeper.server.quorum.QuorumPeerMain /etc/zookeeper/conf/zoo.cfg

Nothing helps.

You could try:

sudo service zookeeper stop

to stop the process. If it does not work you could check this link:

Stop ZooKeeper. On the ZooKeeper host machine, execute the following command:

su - zookeeper -c "export ZOOCFGDIR=/etc/zookeeper/conf ; export ZOOCFG=zoo.cfg ;source /etc/zookeeper/conf/zookeeper-env.sh ; /usr/lib/zookeeper/bin/zkServer.sh stop"

If above commands do not stop the Zookeeper and the kill -9 is also not able to stop then there is perhaps a zombie process. You could check this Q&A how to stop such processes if that is the case.

"sudo service zookeeper stop" worked perfectly! Thank you. – merlin Aug 20 '15 at 05:43

From the zookeper root directory (cd ~/zookeeper-3.4.6) run the following command

sudo bin/zkServer.sh stop

bin/zookeeper-server-stop.sh did not work on Mac. And a new process was getting spawned when trying to kill the process, even with SIGTERM.

Instead, stop ZooKeeper with Homebrew:

$ brew services stop zookeeper

The question was: '... on Ubuntu'. So anything using `brew` will certainly not apply. – Patrick Mevzek Oct 12 '18 at 15:49

Personally, I set an environment variable of $KAFKA_HOME - makes my life easier. If you do, you can create an alias for these sorts of things in the following manner:

alias zstop='sudo $KAFKA_HOME/bin/zookeeper-server-stop.sh'

And then you can just type

zstop

Or, if you installed into /opt/kafka for example, you could just type:

sudo /opt/kafka/bin/zookeeper-server-stop.sh

I also like to create an alias to start zookeeper, here are two lines I added to the bottom of my ~/.bashrc file:

alias zstart='$KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties'
alias zstop=''$KAFKA_HOME/bin/zookeeper-server-stop.sh'
