Hi Olivier, Is this approach considered an in place upgrade of the OS? We need to upgrade to RHEL7 from RHEL6 and our system team doesn't use any configuration management tools to do an in place upgrade. It sounds like the systems/hosts in the cluster will be wiped to do the OS upgrade. Do you have any information on how to do this and preserve the Hadoop data disks? We also need to upgrade from HDP 2.5.3 to 2.6.0 and our cluster is kerberized. What's the best approach for us to take in upgrading the OS and HDP simultaneously? ... View more

E.g instead of rm -f /var/lib/smartsense/hst-gateway/keys/*.crt I used rm -f /usr/hdp/share/hst/hst-gateway/keys/*.crt Thanks for posting the solution. ... View more
