Hello all, Finally found the root cause... /Etc/hosts 192.168.0.10 master1.customerdomain.com # Hostname Master1 This is the discrepancy, setting the hostname to the same as shown in /etc/hosts, the issue was solved. Command used: # hostnamectl set-hostname master1.customerdomain.com Then restarted the agent daemon and services in the cluster. Many thanks to the community for so many clues.

Hello, im using rhel8.4 but still the same. The etc/sysconfig/network file is empty but the network still working, im using the etc/hosts wth ips, fqdn and aliases. The nslookup is not working, do i must to have a dns server?? I mean, in a local network configuring etc/hosts don't thik so... Anybody knows how this works and what is the exact commands used for this test? This shouldn't be so difficult, I've read the topics and followed the recommendations but nothing. Many thanks for your help

Hello, It seems the hostname is not enough, the hostname -f is showing the full name wth fqdn, will continue investigating, tanks

Good morning Community, i'm suffering of DNS resolution getting the following fatalistic view every time I access to CM: I'm reading a lot but not getting any robust conclussion of what is the test that concludes in "DNS resolution error". it checks "host's hostname and canonical name" but, what does it means? is it the hostname? the name in the /etc/hosts? In my case, having [root@master1 ~]# hostname master1 [root@master1 ~]# python -c "import socket; print socket.getfqdn(); print socket.gethostbyname(socket.getfqdn())" master1.domain.net 192.168.0.90 does it means the discrepancy between hostname and socket.getfqdn()? I can see how many people is getting this error but not a consistent response, could anyone give the solution here? for trying to understand this common issue? Many thanks in advance.

Hello again, I finally managed to pass by using "custom Repository" and adding the apropriate one, but the issue that I was facing was about using the first option "Cloudera Repository (direct Internet Access)". this should be more automatic, or at least adding possible things to check, because it's not mentioned the allkeys.asc As i'm not using a web or local repo, i'm reaching directly the cloudera one. Many thanks anyway 🙂

Hello, First of all, thanks for your time. then, i'm not creating a local repo, i'm using Cloudera repos with direct internet access, as I can see, the file is in the repo (in Cloudera) and this should be downloaded automatically I think...

Hello Community, Installation is failing because of allkeys.asc not found... This is not mentioned in the installation proccess and not additional config required, why is this happening and how to fix it? why is this not mentioned in the documentation? I can see the file there, is that a bug? Thanks in advance

Hello Community, I would like to rise a big inconsistency about requirements. Starting by the Cloudera Support Matrix that says: CDP Private Cloud Base7.1.8 > will need Cloudera Manager 7.7.1 and OS: RHEL8.4 will work. Now, regarding to NTP, based on teh OS: "In RHEL 8, the NTP protocol is implemented only by the chronyd daemon, provided by the chrony package. The ntp daemon is no longer available. If you used ntp on your RHEL 7 system, you might need to migrate to chrony" in the other hand: https://docs.cloudera.com/cdp-private-cloud-base/7.1.8/kudu-management/topics/kudu-server-management-limitations.html "Kudu releases have only been tested with NTP. Other time synchronization providers such as Chrony may not work." Could someone from Kudu team give some consistency here? RHEL8 not having ntpd anymore but mandatory for KUDU... Please help.

Hello, I wanted to install Impala-shell for remote querying my CDP cluster, but looking with no much success I found the latest impala-shell client is in: archive.cloudera.com/p/cdh7/7.1.2.1/redhat7/yum nothing about 8 version, nothing about my CDP version: 7.1.8... Finally going with this "old" version but now I'm facing these issues: I already have python2 and 3 But not sure what more to try... no information at all in cloudera docs, even in apache impala web page 😞

Hi all, The issue is not related to browsers, simply it has not the option to modify the queues... After many tests I managed to add the queues and resources to the ResourceManager Advanced config: [CM] > Yarn -> Configuration -> ResourceManager -> Fair Scheduler XML Advanced Configuration Snippet (Safety Valve) [CM] > Yarn -> Configuration -> ResourceManager -> yarn.resourcemanager.scheduler.class: org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler by this way the queues are defined.
