The WebUI pages that display the list of map and reduce tasks should also include the hostname where the task is running
------------------------------------------------------------------------------------------------------------------------

Key: HADOOP-4443
URL: https://issues.apache.org/jira/browse/HADOOP-4443
Project: Hadoop Core
Issue Type: New Feature
Components: mapred
Reporter: Jothi Padmanabhan
Priority: Minor
Fix For: 0.20.0


Currently, the page that displays the list of map tasks shows "Task, Complete, Status, Start time, End Time, Counters". If this could show the hostname as well, it could be helpful in analyzing cases where tasks in a given set of nodes execute much slower than the rest.

    -------------------------------------------

    In the case where there are multiple attempts for a task, we could either one row for each attempt or provide a comma separated list of hostnames.
