1 of the 3 node Zookeeper quorum failed, how to add new one back to the quorum

Contributor

We have 3 node Zookeeper quorum, and on of the node was accidently terminated on AWS.

Our cluster is on CDH5.3.3, and it has these services: HDFS, Yarn, HBase, Oozie, Zookeeper. We like to add the node back to the quorum.

 

Beside the node is part of the zookeeper quorum, it also had these roles as well: Hbase Master (fail over successfully),

Yarn Resource Manger (HA - fail over successfully), Journalnode (HA), and Oozie.

Is anyone know how to do it? If you can please provide the steps.

Thanks,

Please follow this steps under "Adding ZooKeeper Roles" to add a new
ZooKeeper server to the existing service. The doc refers to CM4.x but the
steps are still valid in 5.x
