  • Your HDP deployment is successful if the smoke tests for all the components pass successfully. To verify that your map-reduce tasks were successfully completed, browse the web interfaces for the NameNode, JobTracker, and HBase. The default locations for these interfaces are as listed below:

    • NameNode - http://$NameNodeHost:50070/

    • JobTracker - http://$JobTrackerHost:50030/

    • HBase Master Web Interface -http://$HBaseMasterHost:60010/  

  • Test access to the Ganglia server. Browse to the Ganglia server:

    http://$FQDN_for_ganglia_server/ganglia

    where $FQDN_for_ganglia_server is specified in the gangliaserver flat text file.

  • Test access to the Nagios server.

    1. Browse to the Nagios server:

      http://$FQDN_for_nagios_server/nagios

      where $FQDN_for_nagios_server is specified in the nagiosserver flat text file.

    2. Login using the Nagios admin username (nagiosadmin) and password.
