Subject Pipes task being killed
Date Wed, 05 Mar 2008 17:31:52 GMT

We have a Pipes C++ application where the Reduce task does a lot of
computation. After some time the task gets killed by the Hadoop
framework. The job output shows the following error:

Task task_200803051654_0001_r_000000_0 failed to report status for 604
seconds. Killing!

Is there any way to send a heartbeat to the TaskTracker from a Pipes
application. I believe this is possible in Java using
org.apache.hadoop.util.Progress and we're looking for something
equivalent in the C++ Pipes API.
