Hello, a customer has a CDH Express 6.3.1 setup and: - It appears that suddenly one (and just one!) of the hosts listed in Hosts --> All Hosts is now showing as having a complete FQDN. It never used to have it (I have screenshots of previous configurations where ALL hosts in the list are shown with just the hostname and no domain) - Also, there are Stale Configurations waiting to be applied. If I click on them, they are related to a number of Client Configuration files waiting to be deployed, and sure enough ALL the lines in ALL the files are showing a single difference for that particular host! Now, I don't know what happened here. Nobody is reporting a CM configuration change made by them. I don't have History/Rollback capabilities on this cluster, as it's an Express Edition. Also, I have no Audits as well to check what (if any?) parameters have been recently changed I just know that Sysadmins recently performed a change in FQDN names on those hosts at OS level, because a monitoring tool (Zabbix) required it. But according to them nothing has been changed at CM Gui level My questions: - How can I manually check what (if any?) parameters have been recently changed in CM Gui? If I'd be able to identify a change/changes where the FQDN has been put in for that host, I could manually overwrite it - Or maybe the problem could be that CM "detected" a change at OS level (that config made by the sysadmins) and is now proposing a configuration change automatically? I really doubt it, but... Is it even a possibility? Thank you for any advice/help/support. Unfortunately I'm not directly managing that cluster so any requests for screenshots/checks on the system would receive slow replies... I have to ask the Customer. Knowing that, I eventually encourage to simply point out what configurations in CM can lead to change in single host FQDN changes being distributed in the cluster as client configurations
