Adding a Task Node to a cluster

To add a Task Node to a cluster, follow the steps outlined in Adding Nodes to a Cluster, with the following modifications:

  • Packages to install: mapr-tasktracker, mapr-fileserver
  • Before you start the Warden service (which starts the Fileserver service), add the following line to /opt/mapr/conf/mfs.conf:

    mfs.network.location=/compute-only
Note:

After the Fileserver service is running, changing mfs.conf has no effect on the node's topology.
