Timeout value for the RPC from Datanode to SCM.

+ <description>
+ When a heartbeat from the data node arrives on SCM, It is queued for
+ processing with the time stamp of when the heartbeat arrived. There is a
+ heartbeat processing thread inside SCM that runs at a specified interval.
+ This value controls how frequently this thread is run.
+ There are some assumptions build into SCM such as this value should allow
+ the heartbeat processing thread to run at least three times more
+ frequently than heartbeats and at least five times more than stale node
+ detection time. If you specify a wrong value, SCM will gracefully refuse
+ to run. For more info look at the node manager tests in SCM.
+
+ In short, you don't need to change this.
