[jira] [Reopened] (YARN-8014) YARN ResourceManager Lists A
NodeManager As RUNNING & SHUTDOWN Simultaneously
[ https://issues.apache.org/jira/browse/YARN-8014?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bibin A Chundatt reopened YARN-8014:
------------------------------------
> YARN ResourceManager Lists A NodeManager As RUNNING & SHUTDOWN Simultaneously
> -----------------------------------------------------------------------------
>
> Key: YARN-8014
> URL: https://issues.apache.org/jira/browse/YARN-8014
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.8.2
> Reporter: Evan Tepsic
> Priority: Minor
>
> A graceful shutdown & then startup of a NodeManager process using YARN/HDFS v2.8.2 seems to successfully place the Node back into RUNNING state. However, ResouceManager appears to keep the Node also in SHUTDOWN state.
>
> *Steps To Reproduce:*
> 1. SSH to host running NodeManager.
> 2. Switch-to UserID that NodeManager is running as (hadoop).
> 3. Execute cmd: /opt/hadoop/sbin/yarn-daemon.sh stop nodemanager
> 4. Wait for NodeManager process to terminate gracefully.
> 5. Confirm Node is in SHUTDOWN state via: [http://rb01rm01.local:8088/cluster/nodes]
> 6. Execute cmd: /opt/hadoop/sbin/yarn-daemon.sh stop nodemanager
> 7. Confirm Node is in RUNNING state via: [http://rb01rm01.local:8088/cluster/nodes]
>
> *Investigation:*
