Hi sohimankotia,

In order not to strongly rely on the akka implementation, flink implements the heartbeat mechanism for health monitor for the components of TaskExecutor, JobMaster and ResourceManager from FLIP6. So you can see two sets of heartbeat setting, one is for akka internal implementation prefix with `akka` and the other is flink internal implementation.

Best,

Zhijiang

Thanks Zhijiang .

Sorry to ask again . So both set of heartbeats are implementing same feature
.

If Yes , which one has highest priority to detect failure .
If no , can you explain little more or point to some references to
understand difference .

Thanks
Sohi
