Cloudera Manager isn't opening - cloudera

I have an VM: cloudera-quickstart-vm-5.13.0-0-virtualbox, run now.
But the Cloudera Manager's Page isn't being shown.
The message: 'Attempting to connect to Cloudera Manager...'
is being shown the all day.
How Can I solve this problem?

Cloudera manager has to be restarted separately in the quickstart VM. You can run the below command and see it works:
/home/cloudera/cloudera-manager --force --express

Airflow command not found for all commands

I am getting an error when attempting to create a user. I have Airflow running on Unbunto Virtualbox and I am SSH from Visual Studio Code. As a sanity test, I ran airflow scheduler and got a "command not found" again. Attempted to run the command with sudo as well.
Turns out if you are working in the sandbox and close out virtual studio code you need to get back in the sandbox and then run the commands.
>source sandbox/bin/activate
>airflow db init
>airflowebserver

AWS CodeDeploy deployment failed at event ApplicationStop

I am trying to set up auto-deployment from GitHub to AWS, using EC2.
I set Role with CodeDeployServiceRole auto policy
After following the Tutorial: Use AWS CodeDeploy to Deploy an Application from GitHub, my deployment fails at the ApplicationStop event, after trying for couple of minutes with error code HEALTH_CONSTRAINT. I'm not sure how to troubleshoot the issue/where to look.
These are few hints of how you can navigate your way
Logs as mentioned in comments in /var/log/aws/codedeploy-agent
As AWS support recommend you can add for one time --ignore-application-stop-failures so it will skip that step in case it failed last time and see، because the application stop Lifecycle event uses the appspec file from the last successful build so if that one is corrupted somehow this step will fail in the following builds
(not recommended) you can delete the file, that CodeDeploy uses to keep track of the previous successful deployment in the following path /opt/codedeploy-agent/deployment-root/deployment-instructions/
Check the latest logs at /var/log/aws/codedeploy-agent
If your deployment is failing at ApplicationStop event, then most likely the issue is your EC2 instance does not have the necessary permissions to get the artifacts from S3 bucket.
Your EC2 instance must have an IAM role attached which gives it enough permissions to download the artifacts from S3 bucket
Your EC2 must be started with an IAM role. So you may have to reboot your instance after attaching the role to it.
From your configuration, looks like you have provided permissions to CodeDeploy to perform certain actions on your EC2. You may want to check if your EC2 also has the necessary permissions to download packages from S3 bucket.
Another reason for this error is that the CodeDeploy Service is not running on your machine. On Windows machines, Code Deploy Service terminates sometimes, and as a result, the deployment is not downloaded on the machine. Nothing appears in the logs either.
Run services.msc and check the code deploy agent service. If it is not running, start it and retry the deployment.
I had the same issue and solved it by solving codedeploy-agent that wasn't working on my EC2 instance.
sudo service {httpd/apache2} status
Something might have cause the agent not to run properly
Hope it will help
I had the same issue. You also need to make sure that your EC2 instance has code-deploy-agent installed.
Follow the below aws guide. It worked for me.
AWS guide to install code agent in linux server
Check if the codedeploy-agent is running.
sudo service codedeploy-agent status
if not running then use below command to run
sudo service codedeploy-agent start
If you are using aws Windows server, check the logs at :
C:\ProgramData\Amazon\CodeDeploy\log\codedeploy-agent-log.txt
AWS Docs
To check if the codedeployagent running in windows. Open powersheel command window and run these command.
powershell.exe -Command Get-Service -Name codedeployagent
Better to stop and start again.
powershell.exe -Command Stop-Service -Name codedeployagent
powershell.exe -Command Start-Service -Name codedeployagent
Or Restarting also works
powershell.exe -Command Restart-Service -Name codedeployagent
For me I had to uninstall the codedeployagent on windows by uninstalling and deleting old files of codedeploy.
Run the below command in powershell one by one to uninstall.
wmic
product where name="CodeDeploy Host Agent" call uninstall /nointeractive
exit
After this delete the codedeploy folder at this location.
C:\ProgramData/Amazon/CodeDeploy/
Now install codedeployagent on windows.
Start the codedeployagent again.
powershell.exe -Command Start-Service -Name codedeployagent

Missing value auth-url required for auth plugin password

I am trying to install openstack using devstack on ubuntu 16.04.
I followed the following link.
https://docs.openstack.org/developer/devstack/guides/single-machine.html
When I run
sudo openstack service list
, it prompt the following error.
Missing value auth-url required for auth plugin password
Make sure you are logged into horizon and download the rc file (right corner). After that do source admin-openrc.sh
Note that you have to download the rc file of the project you are working on
This should do. keystonerc_admin file is generated at the end of openstack packstack installation
source keystonerc_admin
always run admin-openrc file before running any openstack command
eg.
$source admin-openrc
then run whatever openstack command you want to run
eg.
$openstack --debug server list
Take rocky version of OpenStack Keystone as an example. https://docs.openstack.org/keystone/rocky/install/keystone-openrc-rdo.html#using-the-scripts
You can create an admin-openrc.sh (If you are installing OpenStack Keystone for the first time.) and put environment params. And source this file before you run any "openstack" command. This resolves the issue.
I put the admin-openrc.sh in directory /usr/share/keystone/admin-openrc.sh for a recommend.

upgrading cloudera manager from cdh 5.4.9 to 5.6.0

when i'm trying to upgrade cloudera manager via CM parcel page (at: http://hostname:7180/cmf/parcel/status) i get the flowing errors:
Local parcel error for parcel CDH-5.6.0-1.cdh5.6.0.p0.45-el6.parcel : The version 5.6.0-1.cdh5.6.0.p0.45 is too new to be supported. Please upgrade Cloudera Manager to at least 5.6.0 before using this parcel..
when trying to activate the parcel i get the following error:
The new version of CDH: '5.6.0-1.cdh5.6.0.p0.45' is newer than the running Cloudera Manager version: '5.4.8'.
how can i fix that?
It seems your cloudera manager is older version. So first update your manager then try to upgrade your cluster. Refer below link for more details
