Subject: how to determine if a map task is remote or local

Hi,

I need to determine if a map task performs local or remote input
reads. In other words, is it scheduled on the same node where its
input split located?

I've looked into job history log (at /user/history/done/.../*.jhist)
but found no such info there. Can I get it from some other log?

Igor
