Resolution: Not A Problem
Fix Version/s: (was: 0.24.0)
Status: Resolved (was: Patch Available)
No longer a problem in MR2. I guess we can close this.
The maxRunningTasks property of the LimitTasksPerJob scheduler is ambiguous
in its description, and must be updated
---
Key: MAPREDUCE-2640
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2640
Project: Hadoop Map/Reduce
Issue Type: Task
Components: documentation
Affects Versions: 0.20.2
Reporter: Harsh J
Assignee: Harsh J
Labels: doc
Attachments: 0.22-MAPREDUCE-2640.r1.diff,
0.23-MAPREDUCE-2640.r1.diff, MAPREDUCE-2640.r1.diff
The property's entry in mapred-default.xml is like so:
{code}
property
namemapreduce.jobtracker.taskscheduler.maxrunningtasks.perjob/name
value/value
descriptionThe maximum number of running tasks for a job before
it gets preempted. No limits if undefined.
/description
/property
{code}
There is no mention that this is a property exclusive to the LimitTasksPerJob
scheduler alone. The doc ought to be updated to note that unless there's a
plan of reusing such a property (I do not see fair or capacity schedulers
utilizing this, and they use their own configs).
