             Summary: Expose metrics of NodeNotChosenReason to JMX
                 Key: HDFS-16376
                 URL: https://issues.apache.org/jira/browse/HDFS-16376
             Project: Hadoop HDFS
          Issue Type: New Feature

In our cluster, we can see logs for nodes that are not chosen. But it's hard to see the percentages in each reason from the logs. It is best to add relevant metrics to monitor the entire cluster.
