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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
