[jira] [Updated] (YARN-10887) Investigation: Decouple capacity and
max-capacity modes
[ https://issues.apache.org/jira/browse/YARN-10887?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Szilard Nemeth updated YARN-10887:
----------------------------------
Parent: YARN-10496
Issue Type: Sub-task (was: Improvement)
> Investigation: Decouple capacity and max-capacity modes
> -------------------------------------------------------
>
> Key: YARN-10887
> URL: https://issues.apache.org/jira/browse/YARN-10887
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Szilard Nemeth
> Priority: Major
>
> Currently Fair Scheduler supports the following 3 kinds of settings:
> * Single percentage (relative to parent) i.e. "X%"
> * A set of percentages (relative to parent) i.e. "X% cpu, Y% memory"
> * Absolute resources i.e. "X mb, Y vcores"
> Please note, that the new, recommended format does not support the single percentage mode, only the last 2, like: “vcores=X, memory-mb=Y” or “vcores=X%, memory-mb=Y%” respectively.
> It is recommended that all three formats are supported for maximum-capacity in CS after introducing weight mode.
