Add an "extra data" field to Task for use by Mesos
--------------------------------------------------
Key: MAPREDUCE-2141
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2141
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Matei Zaharia
Assignee: Matei Zaharia
Priority: Minor
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.
