Viewing the Cluster Installation Status Using the Command Line Interface

Use Warden to see the status of MapR services after installation.

  1. Log in to a cluster node.
  2. Use the following command to list MapR services:
    $ maprcli service list
    logpath                                displayname       name             state
    /opt/mapr/logs/mfs.log                 FileServer        fileserver       0
    /opt/mapr/hadoop/hadoop-2.7.0/logs     ResourceManager   resourcemanager  0
    /opt/mapr/hadoop/hadoop-2.7.0/logs     JobHistoryServer  historyserver    0
    /opt/mapr/logs/cldb.log                CLDB              cldb             0
    /opt/mapr/logs/nfsserver.log           NFS Gateway       nfs              0
    /opt/mapr/hadoop/hadoop-2.7.0/logs     NodeManager       nodemanager      0
    /opt/mapr/logs/gateway.log             GatewayService    gateway          0
    /opt/mapr/logs/hoststats.log           HostStats         hoststats        0
    /opt/mapr/apiserver/logs/apiserver.log APIServer         apiserver        0
    $ maprcli license list
    $ maprcli disk list -host <name or IP address>
  3. Next, restart Warden on all remaining nodes using the following command:
    service mapr-warden restart

    Warden is then responsible for starting the rest of the services configured on each node.
