Hi All, We have observed that whenever VCores Total equals to VCores Used, total memory in RM UI shows incorrect memory. We have checked and all the NodeManagers are up. Is this a expected behavior/Bug? Regards, Shyam

Hi @apatel can you validate the custom yarn-site properties once again. yarn.timeline-service.http-authentication.proxyuser.<AMBARI_SERVER_PRINCIPAL_USER>.groups=* yarn.timeline-service.http-authentication.proxyuser.<AMBARI_SERVER_PRINCIPAL_USER>.hosts=* yarn.timeline-service.http-authentication.proxyuser.<AMBARI_SERVER_PRINCIPAL_USER>.users=*

@Aditya Sirna Thanks for the response. Could there be any downside of skipping the service check during rolling upgrade.

We are now sure that we can't remove the clients from Datanodes as our applications will start failing. So, is there any way we can skip the service checks during the rolling upgrade process.

Hello All, We have a cluster with 160+ nodes. We are planning for an rolling upgrade from HDP 2.5 to 2.6 using ambari. We have edgenodes where all the clients has been installed. In addition, we also have clients installed on all the datanodes (150+ nodes) like HDFS client, Zookeeper client etc. If you review the below link, we could see that ambari does validate the services multiple times by running service checks during upgrade process. https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-upgrade/content/upgrading_HDP_perform_rolling_upgrade.html This will consume a lot of time during the upgrade. We can minimize the time by limiting the clients service checks. Do we really need all the clients to be installed on the datanodes? If we remove the clients from datanodes, will there be any impact on the cluster in terms of functionality. If there is no impact then what all clients can be removed . Appreciate your input!!

Hi @Shaun Michael I haven't configured external hive metastore on HDC. Have you gone through the below article by @Dominika Bialek which explained "How to set up shared RDS as Hive or Druid metastore on Hortonworks Data Cloud for AWS".

Hi, @sachin gupta Are you using AD Kerberos or MIT? When you try to access Web UI, it will ask for username/password. We had AD Kerberos in our environment. We were passing username (after successful kinit for that user) in the username field and password for that user and receiving error "GSSHeader did not find the right tag". Here you need to pass your realm along with the username in username field like username@<REALM>. Also, check you JDK version.

Hi @pavan p Could you please check/tail the nodemanager log on worker node (w2) when you start it and see if you are getting any ERROR or WARN message in it.
