> Even after specifying {{yarn.containers.vcores}} and having Flink request such a container from YARN, it may not take these into account at all and return a container with 1 vcore.
> The YARN configuration needs to be adapted to take the vcores into account, e.g. by setting the {{FairScheduler}} in {{yarn-site.xml}}:
> {code}
> <property>
>   <name>yarn.resourcemanager.scheduler.class</name>
>   <value>org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler</value>
> </property>
> {code}
> This fact should be documented at least at the configuration parameter documentation of  {{yarn.containers.vcores}}.
