Developer/Data Engineer Troubleshoot Problems and Errors

Problem: Java: Windows ignores JAVA_HOME

Symptom: Windows ignores JAVA_HOME

Resolution:

The Java installer will put a copy of java.exe (but no libraries) in the C:\Program Files (x86)\Common Files\Oracle\Java\javapath directory and add that directory to the beginning of the PATH variable.

If you don"t use a full path, the copy of java.exe to run is found by using the PATH system variable. Since this directory doesn"t contain the DLLs of a particular Java runtime version, one is located one by looking at the registry.

So, you either need to modify the registry, or replace the javapath entry with the version of Java you want in your PATH system (not user) variable.

Recommend setting registry

    Computer\HKEY_CURRENT_USER\Environment\JAVA_HOME
    C:\apps\Java\jdk1.8.0_333

Problem: NPM Won't Run After Upgrade

Problem: NPM Won't Run After Upgrade using a manual install

Reference: Stack Overflow

Solution:

If npm is no longer installed in /usr/bin/npm, then chances are good bash(1) has hashed the executable name. The hashing saves repeated searches of all directories in your PATH every time you execute common programs. Since programs almost never change directories, this is usually a great idea. To fix this isue, remove the hash by running the following command:

hash -r.

Problem: WSL: Ubuntu: Unable to reset WSL root password in Ubuntu

Symptom: Unable to reset WSL root password in Ubuntu

Reference: AskUbuntu

Solution:

1. Open cmd.exe
2. Type:

wsl -u root

3. Change the password:

passwd username

4. Type:

exit

5. Type:

wsl

6. Confirm the new password works:

Error: Azure B2C: The subscription is not registered to use namespace 'Microsoft.AzureActiveDirectory'

Symptom: Receive error when creating an Azure B2C tenant: The subscription is not registered to use namespace 'Microsoft.AzureActiveDirectory'. See https://aka.ms/rps-not-found for how to register subscriptions.

Reference: Blog

Resolution:

1. Login to azure. Start up a shell and type the following command.

   az login
   

   This will start up a browser and you will need to log into Azure.

2. Get subscription list. If you have one subscription then the default will be selected. If not then you will need to check your subscriptions and then set the right one. Using the account list command you can get a list of your subscriptions.

   az account list
   

   You will get a list of subscriptions that you have access to. You can then set the subscription you want to work on.

3. Set the subscription to work on.

   az account set --subscription "ZFI4-PERSONAL-DEV"
   

4. Register the namespace provider

   az provider register --namespace Microsoft.AzureActiveDirectory
   

Error: Azure: ClientSecret: Secret should be an Azure Active Directory application's client secret

Symptom: Receive error: secret should be an Azure Active Directory application's client secret when calling function: credential = ClientSecretCredential(tenant_id, client_id, client_secret)

Resolution:

    - If running from local jupyter notebook ensure you have set the local python environment for your project: Example: OD_NHANES_DEV
    - Use the client secret of the service principal, not the client secret of the app registration.
    - Ensure that the client secret of the service principal is set in the system environment variable for your application: Example: LAVA_OD_NHANES_DEV_AZURE_CLIENT_SECRET

Error: Databricks: Error in SQL statement: SecurityException: User does not have permission SELECT on any file

Symptom: Table creation fails in Databricks with security exception: Error in SQL statement: SecurityException: User does not have permission SELECT on any file.

Reference: Databricks KB

Solution:

Run the following command:

GRANT SELECT ON ANY FILE TO `user1`

Warning

It is important to understand the security implications of granting ANY FILE permissions on a filesystem. You should only grant ANY FILE to privileged users. Users with lower privileges on the cluster should never access data by referencing an actual storage location. Instead, they should access data from tables that are created by privileged users, thus ensuring that Table ACLS are enforced.

In addition, if files in the Databricks root and data buckets are accessible by the cluster and users have MODIFY privileges, the admin should lock down the root.

Error: Ubuntu: Failed to call method: org.freedesktop.DBus.Properties.Get: object_path= /org/freedesktop/UPower: org.freedesktop.DBus.Error.ServiceUnknown

Problem: When browsing https://127.0.0.1:5000 receive error: SSL: Handshake failed. while not logged into ZScaler

Solution:

Here are the steps you can follow to fix this error:

1. Check if the UPower daemon is installed on your system by running the following command in the terminal:

   systemctl status upower.service
   

   If the command output shows that the UPower service is not running or is not installed, you can install it using the package manager for your system (e.g. apt-get for Ubuntu/Debian, dnf for Fedora, pacman for Arch Linux, etc.).

2. Install the UPower daemon using the package manager. For example, on Ubuntu/Debian, you can run the following command:

   sudo apt-get install upower
   

   This command installs the upower package, which provides the UPower daemon.

3. After installing the UPower daemon, start the service using the following command:

   sudo systemctl start upower.service
   

4. Verify that the UPower daemon is now running by checking the status using the following command:

systemctl status upower.service

5. Restart your Flask application and try again. The error message should no longer appear.

Note that the specific steps for installing and starting the UPower daemon may vary depending on your system and distribution. You may need to consult the documentation or package manager for your system to find the appropriate package and commands to install and start the UPower daemon.

Solution:

1. Verify that your Python installation has a valid CA bundle that can be used to verify the SSL/TLS certificate. You can do this by running the following command in your terminal:

python -c "import ssl; print(ssl.get_default_verify_paths())"

This should print out the paths to the CA bundle and the OpenSSL configuration file used by Python. If the paths are not found or are invalid, you may need to update your Python installation or install a valid CA bundle.

Path should return

/usr/lib/ssl/certs

2. Download the missing CA certificate from the server that issued the certificate. You can use the openssl s_client command to retrieve the certificate, like this:

cd $HOME
openssl s_client -showcerts -connect clientservices.googleapis.com:443 </dev/null 2>/dev/null | openssl x509 -outform PEM > clientservices.googleapis.com.crt
openssl s_client -showcerts -connect optimizationguide-pa.googleapis.com:443 </dev/null 2>/dev/null | openssl x509 -outform PEM >  optimizationguide-pa.googleapis.com.crt
openssl s_client -showcerts -connect safebrowsing.googleapis.com.com:443 </dev/null 2>/dev/null | openssl x509 -outform PEM >  safebrowsing.googleapis.com.crt
openssl s_client -showcerts -connect accounts.google.com:443 </dev/null 2>/dev/null | openssl x509 -outform PEM >  accounts.google.com.crt
openssl s_client -showcerts -connect update.googleapis.com:443 </dev/null 2>/dev/null | openssl x509 -outform PEM >  update.googleapis.com.crt
openssl s_client -showcerts -connect www.google.com:443 </dev/null 2>/dev/null | openssl x509 -outform PEM >  www.google.com.crt
 dns.google

3. Install the CA certificate in your system's trusted CA store by copying it to the /usr/local/share/ca-certificates/ directory:

sudo cp clientservices.googleapis.com.crt /usr/local/share/ca-certificates/
sudo cp optimizationguide-pa.googleapis.com.crt /usr/local/share/ca-certificates/
sudo cp  safebrowsing.googleapis.com.crt /usr/local/share/ca-certificates/
sudo cp accounts.google.com.crt /usr/local/share/ca-certificates/
sudo cp update.googleapis.com.crt /usr/local/share/ca-certificates/
sudo cp www.google.com.crt /usr/local/share/ca-certificates/

4. Update the CA bundle by running the following command:

sudo update-ca-certificates

Symptom: Receive error: curl: (60) SSL certificate problem: unable to get local issuer certificate when installing docker

Reference: Stack Overflow

Details:

The problem may be related to the way the firewall is handling certificates. The certificate of the firewall may be untrusted/unknown from within the wsl environment.

Resolution:

Option 1:

1. If logged into zscaler, log out
2. Try Again

Option 2:

Export the firewall certificate.

1. Export the firewall certificate from the windows certmanager (certmgr.msc).
2. The certificate may be located at "Trusted Root Certification Authorities\Certifiactes"
3. Export the certificate ZScaler Root CA as a DER coded x.509 and save it under e.g. "_templates/certs/zscaler.cer".

Configure WSL.

    open wsl terminal from VS Code : should default to Ubuntu: directory "/Users/zfi4/OneDrive - CDC/LAVA Analytics/davt-dev-jcbowyer"
