@manojSinghK  I obviously don't have access to your logs to prove it, but I strongly suspect that you haven't encountered the issue you're having now upon service restarting in the past because in the past the repo Ambari is set to retrieve files from was publicly accessible, and now it is not. Since the file retrieval necessary to complete the HDFS client install step fails, it appears as if your existing cluster is being impacted.   If you want your installation of Ambari to continue retrieving files from the location where it appears that you have Ambari set to retrieve them (i.e., Cloudera's repositories) after January 31, 2021, you will have to have a a valid Cloudera Subscription.   Again, please read the announcement here: Transition to private repositories for CDH, HDP and HDF.   The same announcement describes new patch releases of Ambari, 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 HDP cluster.     ...
