[jira] [Created] (SPARK-7598) Add aliveWorker metrics in Master

Rex Xiong created SPARK-7598:
--------------------------------

             Summary: Add aliveWorker metrics in Master
                 Key: SPARK-7598
                 URL: https://issues.apache.org/jira/browse/SPARK-7598
             Project: Spark
          Issue Type: Improvement
          Components: Deploy
    Affects Versions: 1.3.1
            Reporter: Rex Xiong
            Priority: Minor


In Spark Standalone setup, when some workers are DEAD, they will stay in master worker list for a while.
master.workers metrics for master is only showing the total number of workers, we need to monitor how many real ALIVE workers are there to ensure the cluster is healthy.
