Starting ZooKeeper and Warden brings up the cluster.
Depending on the options that you specified when running
configure.sh, Zookeeper and Warden might
already be started.
Note: For a DARE-enabled cluster, you can skip this step
because you already started the cluster in order to configure disk storage.
To check that Zookeeper is started, use this command (Zookeeper nodes
only):
service mapr-zookeeper status
To check that Warden is started:
service mapr-warden status
To start the cluster if Zookeeper and Warden are not started:
- Start ZooKeeper on all nodes where it is installed, by issuing the following
command:
service mapr-zookeeper start
- Start Warden on all nodes:
service mapr-warden start
