Reset heartbeat when resetting layer.
Reset heartbeat when resetting layer.

When we reset a layer we also need to reset the heartbeat status. This field
is used to note that a failed EMR heartbeat was returned and we rely on
knowing that two failed heartbeats were returned to decide if the cluster
actually failed to complete the job.
