    Description

      We have added these configs on yarn-site.xml file of our Hadoop-Yarn cluster.

      <property>
          <name>yarn.nodemanager.recovery.enabled</name>
          <value>true</value>
      </property>
      <property>
          <name>yarn.nodemanager.recovery.supervised</name>
          <value>true</value>
      </property>
      

      The NM restart recovery feature has been working well, applications not failing even if we restart nodemanager processes. But, when we try to decommission a node by adding the node name to yarn_exclude_hosts file and refreshing nodes on resourcemanager, the applications that had containers running on that node are stuck for a long time and then fail.
