Deleting a failed node/host

Deleting a failed node/host

Contributor

I am running HDP-2.5.3.0, ambari 2.4.2.0

I have a cluster node/host that died over the weekend and I am not able to resurrect it

Through ambari I am able to put it in maintenance mode.

 

I would like to delete this node from the cluster.  It's role was datanode and yarn Nodemanager.

Went choosing the delete option for Host Actions I get a warning that the DataNode and Nodemanager should be decommissioned first to prevent loss but those options are not available via ambari.

 

Is there another option for decommissioning or is my only option to delete given the status of the node? 

Thanks.
