Subject Query about Speculative Execution
Date Thu, 06 Dec 2012 14:57:44 GMT

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.
