    • Release Note:
      Improved grouping of Hadoop metrics and Chukwa metrics.

      Description

      Metrics emited by Chukwa Agent through MetricsContext is structured as:

      contextName: chukwaHttpSender
      recordName: chukwaHttpSender

      The same context is repeated twice in the naming hierarchy.

      Ideally, the structure should be:

      contextName: chukwaAgent
      recordName: httpSender

      Therefore, the metrics can be collected in chukwa table, column family: agent_httpSender. In sequence file, it will be chukwa data type directory, and hashmap looks like:

      { "contextName":"chukwaAgent","recordName":"httpSender",...}
