--------------------------------
Summary: Fair Scheduler configuration defaults are not documented
in case of min and maxResources
Key: YARN-9326
URL: https://issues.apache.org/jira/browse/YARN-9326
Project: Hadoop YARN
Issue Type: Improvement
Components: docs, documentation, fairscheduler, yarn
Affects Versions: 3.2.0
Reporter: Adam Antal
Assignee: Adam Antal
The FairScheduler's configuration has the following defaults (from the code:
javadoc):
{noformat}
In new style resources, any resource that is not specified will be set to
missing or 0%, as appropriate. Also, in the new style resources, units are not
allowed. Units are assumed from the resource manager's settings for the
resources when the value isn't a percentage. The missing parameter is only used
in the case of new style resources without percentages. With new style
resources with percentages, any missing resources will be assumed to be 100%
because percentages are only used with maximum resource limits.
{noformat}
This is not documented in the hadoop yarn site FairScheduler.html. It is quite
intuitive, but still need to be documented though.
