Subject Re: IPC ephemeral ports

Hi,

It’s there in /etc/hadoop/conf.empty/yarn-site.xml

<property>
      <name>yarn.app.mapreduce.am.job.client.port-range</name>
      <value>40000-40050</value>
 </property>

I can try to restart all services, but this property was provided in the blueprint, so i think
Ambari already used it at the first start.

Most likely you have verified it but is the yarn-site modified on all nodes  
and node manager restarted?
