After installed HDP, we just realized that multi-thread on bios wasn't enabled on one server. So we did enable it but on Ambari it still show the old CPU(cores) information. How to get information refresh/updated?
Where are you checking in Ambari? Can you share the screenshot? Is it the Hosts page you are checking the number of CPUs?
Have you tried restarting Ambari Agent on that host?
Thank you for your reply, I've tried restart Ambari-Agent but it's still the same.
