             Summary: codahale base Metrics data between applications can jumble up together
                 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.
