[jira] [Commented] (AMBARI-5847) Nodemanager is running on nodes
that were not chosen during installation
[ https://issues.apache.org/jira/browse/AMBARI-5847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14005156#comment-14005156 ]
Sudhir Prakash commented on AMBARI-5847:
----------------------------------------
I noticed that immediately after the install, Nodemanger is started on the correct nodes. However, nodemanager is configured to start on boot on ALL nodes. So after rebooting nodes, Nodemanager is running on aLL nodes.

> I performed an installation using the Ambari GUI and chose to install Nodemanger only on my 4 Datanodes. However, when I do "ps aux | grep nodemanager", I see Nodemanger is running on all 7 of my nodes.
> The Ambari GUI reports that 4/4 Nodemangers are running.
> Example out put from my Master #1 node:
