             Summary: RBF supports healthMonitor timeout configurable and cache NN and client proxy in NamenodeHeartbeatService
                 Key: HDFS-16705
                 URL: https://issues.apache.org/jira/browse/HDFS-16705
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: ZanderXu
            Assignee: ZanderXu


When I read NamenodeHeartbeatService.class of RBF, I feel that there are somethings we can do for NamenodeHeartbeatService.class.
 * Cache NameNode Protocol and Client Protocol to avoid creating a new proxy every time
 * Supports healthMonitorTimeout configuration
 * Format code of getNamenodeStatusReport to make it clearer
