Query about Speculative Execution

What is the behavior of jobTracker if speculative execution is off and a task on data node is running extremely slow?
Will the jobTracker simply wait till the slow running task finishes or it will try to heal the situation? Assuming that heartbeat from the node running slow task are regular.
