I am having trouble with a zookeeper ensamble where one node is not able to join the quorum. Zookeeper will not join the cluster. How to apply patch/upgrade? This seems to be related to a bug which has been fixed in 3.4.6
Now the question is, how to upgrade within Ubuntu 14.04.3? I have already done apt-get update
and apt-get upgrade
and apt-get dist-upgrade
, but the version still is Zookeeper version: 3.4.5--1, built on 06/10/2013 17:26 GMT
This is a production environment and it is important that the service stays live. Right now it is operational with 2 zookeeper nodes.

The zookeeper service is a java process executing
/usr/share/java/zookeeper.jar
, which is a symlink to/usr/share/java/zookeeper-3.4.5.jar
. I have downloaded the new version of zookeeper, stopped the service, copied the new jar to/usr/share/java/
and pointed the symlink to the new jar, then started the service:
