Subject [jira] Updated: (HADOOP-4178) The capacity scheduler's defaults for queues should be configurable.
Date Wed, 17 Sep 2008 04:43:44 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4178?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Sreekanth Ramakrishnan updated HADOOP-4178:

    Attachment: HADOOP-4178-1.patch

Configuration for the following default queue parameter should are added to the capacity_scheduler.xml.

- Default Guaranteed Capacity: _mapred.capacity-scheduler.default-guaranteed-capacity_
- Default Reclaim time limit: _mapred.capacity-scheduler.default-reclaim-time-limit_
- Default priority supported: _mapred.capacity-scheduler.default-supports-priority_
- Default User limit:: _mapred.capacity-scheduler.default-minimum-user-limit-percent_

Modified the test case in order to write out default configuration which is required by the
_CapacitySchedulerConf_ add a new test case to test the default parameter setting.

Removed an empty method from _CapacitySchedulerConf_ and implemented logic for reading defaults
first in the _CapacitySchedulerConf_
