Hello @jsensharma, Thank you for your reply, I was able to successfully restart Yarn DNS Registry but the upgrade still shows the same error - unhealthy host. I checked the host component state in Ambari database and found that the Yarn registry is in Failed state. YARN_REGISTRY_DNS | UNKNOWN | STARTED | 15 | YARN | FAILED

Hello All,
When upgrading HDP cluster to 3.1.0 version -Restarting yarn DNS resgistry failed due to ERROR 'resource_management.core.exceptions.ExecutionFailed: Execution of 'ambari-sudo.sh -H -E /usr/hdp/3.1.0.0-78/hadoop-yarn/bin/yarn --config /usr/hdp/3.1.0.0-78/hadoop/conf --daemon start registrydns' returned 1. ERROR: Cannot set priority of registrydns process 123223'.
I ignored it and proceeded with the upgrade. But at Finalize Pre check the task failed and the only option available is to delete the unhealthy and host and proceed with the upgrade.
How can I resolve this issue.

Hello All,
I've installed CM manager 6.3.0 and agents in my 7 node cluster. While setting up the CDH 6.3.1 installation, i'm stuck at setup database step, where the test connection is running for more than 2 hours, with only info found in Cloudera manager log given below.
There is no error or any other information. I can successfully connect to my databases from command line. But CM is unable to verify the connections.
Any help will be appreciated.

I have loaded 6 files in my oozie workflow. Out of 6, 4 work flow succeeded but two of them are in suspended state. When I checked the log then I am getting file not found "FNF: Required local file /var/tmp/oozie/xxxx/ssh/ssh-base.sh not present" error. If I resume the job it works. all the 6 work flow are the same. I have loaded all the files for the 6 work flow at the same time. Work flow 1,2 succeeded 3and 4 suspended 5 and 6 succeeded. Please share your thoughts.
