> Key: SPARK-3377
> URL: https://issues.apache.org/jira/browse/SPARK-3377
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.1.0
> Reporter: Kousuke Saruta
> Priority: Critical
>
> I'm using codahale base MetricsSystem of Spark with JMX or Graphite, and I
> saw following 2 problems.
> (1) When applications which have same spark.app.name run on cluster at the
> same time, some metrics names jumble up together. e.g,
> SparkPi.DAGScheduler.stage.failedStages jumble.
> (2) When 2+ executors run on the same machine, JVM metrics of each executors
> jumble. e.g, We current implementation cannot distinguish metric "jvm.memory"
> is for which executor.
