-------------------------------
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
