2016-11-29T23:23:05

I have one master one worker cluster. I am upgrading to YARN from Hadoop classic. resourcemanager and historyserver successfully started, but nodemanager is not starting it is giving error

java.lang.NumberFormatException: For input string: "${nodemanager.resource.memory-mb}"

I have kept same yarn-site.xml.template in both server.

I have replaced ${nodemanager.resource.memory-mb} to 8192

<configuration>
  <property>
    <name>yarn.resourcemanager.hostname</name>
    <value>__RM_IP__</value>
  </property>
  <property>
   <name>yarn.resourcemanager.scheduler.address</name>
   <value>${yarn.resourcemanager.hostname}:8030</value>
  </property>
  <property>
   <name>yarn.resourcemanager.resource-tracker.address</name>
   <value>${yarn.resourcemanager.hostname}:8031</value>
  </property>
  <property>
   <name>yarn.resourcemanager.address</name>
   <value>${yarn.resourcemanager.hostname}:8032</value>
  </property>
  <property>
