Hi, Based on the posts in the community, looks like physical servers are recommended rather than VM cluster. Now i would like to know what is the best practice for scale out the servers and what memory, cpu and disk is recommended . Looks like it is also recommended to scale out (multiple machines) rather than scale up ( smaller number of large machines). Can you please advise more details about the best practice for scale out the HDP and HDF servers? Thanks, SJ ... View more

Hi, I've launched HDP 2.5 on an AWS instance, for some reason i cannot login to admin. I wanted to reset the admin ambari password, i tried "ambari-admin-password-reset" but looks like it is for sandbox and it cannot found on the server. Please advise how can I reset the password.
