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.

Hi,

If map task is unexpectedly "silent" for a long time (e.g. wait for
other application response), What happen? Is there any limit for
staying?

Thanks

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
