Install OpenJDK

$ sudo mkdir /var/lib/zookeeper

$ cd /var/lib

$ sudo chown zookeeper:zookeeper zookeeper/

$ sudo mkdir /var/log/zookeeper

$ cd /var/log

$ sudo chown zookeeper:zookeeper zookeeper/


Note: While running the zookeeper if you get a message something like below you may need to check/change for permissions of the files under /var/lib/zookeeper and /var/log/zookeeper.

Since I have loged-in as linaro and running zookeeper.  I have changed the permission to linaro user.


linaro@node1:~/drill-setup/zookeeper-3.4.12$ ./bin/zkServer.sh start

ZooKeeper JMX enabled by default

Using config: /home/linaro/drill-setup/zookeeper-3.4.12/bin/../conf/zoo.cfg

Starting zookeeper ... ./bin/zkServer.sh: line 149: /var/lib/zookeeper/zookeeper_server.pid: Permission denied

FAILED TO WRITE PID




Edit the bashrc for the zookeeper user via setting up the following Zookeeper environment variables.

...

Edit zoo.cfg and the below


$ vi zoo.cfg


dataDir=/var/lib/zookeeper
server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888


Now, do the below changes in log4.properties file as follows.

$ vi log4j.properties


zookeeper.log.dir=/var/log/zookeeper 
zookeeper.tracelog.dir=/var/log/zookeeper 
log4j.rootLogger=INFO, CONSOLE, ROLLINGFILE

...

$ /home/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status
