New in This Release

MapR Monitoring in the MEP 4.0.0 release introduces the following enhancements:

  • An upgraded component stack.
  • A default security feature that secures the MapR cluster and supported ecosystem components, including MapR Monitoring, using MapR-SASL and wire-level encryption, as well as the ability to configure custom security.
  • A Spyglass on Streams feature that uses Streams as the default mechanism through which metrics flow from collectd to OpenTSDB.
    Note: Writing to an external OpenTSDB is not supported from release 6.0 onwards.
  • MapR Monitoring now provides metrics for the YARN Resource Manager and Node Manager.



Known Issues and Limitations

See Known Issues at Release (MapR 6.1.0)

Resolved Issues

  • COLD-4: By default, collectd reads files from the custom configuration file directory (/opt/mapr/collectd/conf/) on nodes without support for the wordexp function, eliminating the need to include Filter "*.conf" in the collectd.conf configuration file.
  • SPYG-838: On secure clusters, JMX ports can no longer be accessed without authentication, eliminating the need to setup a password on each Node Manager and Resource Manager node.
  • KIB-1: A syntax error in no longer causes an error message when you run on a node with Kibana installed in a secure cluster.
