Hi @shri
The server archive.cloudera.com is returning an HTTP 401 error because authentication is required. You didn't provide a whole lot of detail about how you went about adding the new host to your cluster, but I would guess that the last time you attempted this operation, you were not challenged for authentication by this particular host at Cloudera and so you're wondering what changed recently.
The answer is probably that your installation of Cloudera Manager isn't set up to supply the authentication credentials. At the tail end of last month, Cloudera changed the download policy and now to download CDH parcels, etc. from Cloudera's repositories you need a valid subscription. Please see the announcement here: Transition to private repositories for CDH, HDP and HDF.
The same announcement describes new patch releases of Cloudera Manager, which are now required to access Cloudera’s private repositories, which now contain the new and legacy releases and other assets such as those necessary to add a new host to an existing CDH cluster.
