Change in fair-scheduler.xml

Hi, We are trying to change properties of fair scheduler settings.

1 - Is there a document on what should be the default settings in the XML
file for say 96 GB.. 48 core system with say 4/queues?

2 - When we change the file does the yarn service need to be bounced for
the changed values to get reflected?

Thanks
Manish

You can refer below the doc for configuring fair scheduler
http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/FairScheduler.html


2 - When we change the file does the yarn service need to be bounced for the changed values to get reflected?
Yarn admin supports runtime refresh queues without restarting ResourceManager.  It can be achieved by  using “$HADOOP_HOME/bin/yarn rmadmin –refreshQueues”  CLI command.
