https://community.cloudera.com/t5/Support-Questions/Decomissioning-a-NodeManager-in-HDP-2-6-1/m-p/328502#M230264 <P>I am trying to decommission a data node. I started by decommissioning the regionserver, and the nodemanger. I have 7 nodes in the cluster. When I followed the steps to remove the one nodemanager it says it was successful. Even though it says 1 was decommissioned 7 are still showing as active. How do I resolve?</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="railincdba_0-1634829497770.png" style="width: 400px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/32719iF6DEC08CA731D50F/image-size/medium?v=v2&amp;px=400" role="button" title="railincdba_0-1634829497770.png" alt="railincdba_0-1634829497770.png" /></span></P><P>&nbsp;</P> Thu, 21 Oct 2021 15:21:33 GMT railincdba 2021-10-21T15:21:33Z https://community.cloudera.com/t5/Support-Questions/Decomissioning-a-NodeManager-in-HDP-2-6-1/m-p/328502#M230264 <P>I am trying to decommission a data node.
