Edward, you can always spawn a thread that will periodically call reporter.progress() and then wait for the (remote/blocking) call to complete. Once the call is complete simply destroy this thread. Hope that helps. Amar Thanks. On Fri, Jun 13, 2008 at 2:18 PM, lohit <[EMAIL PROTECTED]> wrote: Yes, there is a timeout defined by mapred.task.timeout default was 600 seconds.

Re: Map Task timed out?
Yes, there is a timeout defined by mapred.task.timeout default was 600 seconds. And here silent means the task (either map or reduce ) has not reported any status using the reporter you get with map/reduce function Thanks, Lohit - Original Message From: Edward J.
