To fix this we need to edit hdp-select file

# vi /usr/bin/hdp-select

Search for below code

 except ValueError:
        print ("ERROR: Unexpected file/directory found in %s: %s" % (root, f))
        sys.exit(1)

Change it as mentioned below

 except ValueError:
       pass
       #print ("ERROR: Unexpected file/directory found in %s: %s" % (root, f))
       #sys.exit(1)

This has to be done in all nodes or else services may fail while starting in those nodes
