Explains how to add a service to a node.
The process of adding a service to a node is similar to the initial installation
process for nodes. For further detail see
Installing MapR Software.
-
Install the package(s) corresponding to the new role(s) using
apt-get or yum.
-
Run
configure.sh with a list of the CLDB nodes and ZooKeeper nodes
in the cluster.
-
If you added the CLDB or ZooKeeper role, you must run
configure.sh on all other nodes in the cluster.
-
If you added the fileserver role, run
disksetup to
format and prepare disks for use as storage.
-
Restart Warden.
service mapr-warden restart
When Warden restarts, it picks up the new configuration and starts the new services,
making them active in the cluster.
