Starting Up a Cluster
About this task
Procedure
- If the cluster nodes are not running, start them.
-
Change to the
root
user (or usesudo
for the following commands). -
Start the ZooKeeper on nodes where it is installed. Example:
# service mapr-zookeeper start
# service mapr-zookeeper start
-
On all nodes, start Warden. Example:
# service mapr-warden start
# service mapr-warden start

Over a period of time (depending on the cluster size and other factors) the cluster
comes up automatically. After the CLDB restarts, there is a 15-minute delay before
replication resumes, in order to allow all nodes to register and heartbeat. This
delay can be configured using the
config save
command to set thecldb.replication.manager.start.mins
parameter.
