      Description

      Currently metrics from mapreduce tasks are reported using mapreduce framework counters. This looks like a hack:

      • counters info has to be reported as gauges by mr submitter
      • there are limitation on what you can do with counters (incl counter name size, and number of counters, e.g. see CDAP-2787)
      • some of metrics data transfer is redundant

      Instead, what we want is tasks to report metrics as any other YARN container that executes any other program: directly to Kafka.
