removing ZK installation
Hi,
I need to remove ZooKeeper from a Centos machine. I tried yum remove to no avail using instructions I found online.
Thanks.

Find where it is installed - typically /opt/zookeeper.
Also do a which zookeeper to see if it is linked to /usr/bin or some such place.
Make sure zookeeper is stopped.
Far as I recall, Centos has Upstart, so sudo stop zookeeper and sudo disable zookeeper. Or sudo systemctl stop zookeeper and sudo systemctl disable zookeeper.
Then cat the /opt/zookeeper/conf/zoo.cfg to see where the data directories and logs are. Delete the data and log directories.
Then delete /opt/zookeeper.

Could someone please let me know where to get RPM for Centos for Zookeeper.
Thanks

Re: removing ZK installation

Steve, how was zookeeper installed? That should be the method with which you remove it.
If you are not sure how it was installed, you can do:
rpm -qa |grep zookeeper
To determine whether it was installed via an RPM package. If that does not unearth a matching RPM then it was probably installed some other way. More than likely it could have binary in an archive extracted to, maybe, /opt/zookeeper.
If you look at the running zookeeper process it should give you an idea of where zookeeper is installed and where the data directory is:
ps -ef |grep zookeeper
How zookeeper is starting is dependent on which version of Centos you are running. Centos 6 uses upstart and service command. More than likely you will find the zookeeper init script in /etc/init.d. If this is Centos 7 then it's systemd. As root you can run systemctl by itself to get a list of service scripts. Hit the "/" key and type in zookeeper. It will take you to any service script with zookeeper in the name. This will help you determine how to stop zookeeper.
If neither systemd is showing a zookeeper service nor you see a service script in /etc/init.d (or if service zookeeper stop doesn't work), then it would appear that zookeeper was started in some other way, maybe manually without a service or systemd script.
You'll want to figure this out because if you have to manually remove zookeeper, instead of using a package manager like RPM, you'll want to disable any startup scripts from running and throwing errors once Zookeeper is removed.
