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.
