Description

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
