Install HDF on new node

[#1]

I have 4 node cluster where Ambari is on node1 and hdf 2.1.1.0-2 is installed on the cluster. Node2 crashed and now it's not recoverable. I got a new node now and have to do a fresh install of HDF components on this node. What would be the best option to install HDF on this new node.

Hi @Balakrishna Dhanekula

What you need first is to add this node your Ambari managed cluster. This can be done by installing an Ambari agent on this node then adding it to Ambari. Later, you can install components that you want on this new node.

There's a good article on this topic here : https://community.hortonworks.com/articles/80284/hdf-2x-adding-a-new-nifi-node-to-an-existing-secur....

Thanks it worked. I am trying to find how can I remove the crashed node. When I click on delete host it complaining that I should be removing the services on that node. How can I update configs like zookeeper, kafka etc such that their configs doesn't show the dead host.
