Document configurations parameters that are read by MapReduce framework and
cannot be changed per job
-----------------------------------------------------------------------------------------------------
Key: MAPREDUCE-1805
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1805
Project: Hadoop Map/Reduce
Issue Type: Improvement
Affects Versions: 0.20.2
Environment: All
Reporter: Milind Bhandarkar
>From the documentation in mapred-default.xml, it is not apparent whether the
>configurations parameters (such as mapred.tasktracker.map.tasks.maximum) can
>be specified per-job, or whether these parameters are read by the framework at
>start-up and can never be changed. It would be helpful to annotate the default
>configurations file with this information.
