> In order to support running Hadoop on the Mesos cluster manager (http://mesos.berkeley.edu/),
I'd like to add an extra String field to the Task class to allow extra data (a Mesos task
ID) to be associated with each task. This should have no impact on normal operation other
than making the serialized form of Task a few bytes longer. In the Mesos support patch for
Hadoop, this field is set by a pluggable Hadoop scheduler implementation to allow code on
the TaskTracker side to see which Mesos task corresponds to each Hadoop task.
