curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
Note: You will have to wait 20 seconds
  1. Build and Run Image
cd .devcontainerlocal
sudo docker build -t OCIO_PADE_DEV .
sudo docker run -it --rm --name OCIO_PADE_DEV OCIO_PADE_DEV

Option 2: Manual Install

  1. Check that you have WSL version 2
wsl --set-default-version 2
  1. Remove any old docker images
sudo apt remove docker docker-engine docker.io containerd runc
  1. Install/Upgrade dependencies
sudo apt-get update
sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release
  1. Add Docker's official GPG key
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
  1. Add Docker's stable repository
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
  1. Install Docker Engine and Docker Compose
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
  1. Verify Docker Install
sudo docker run hello-world

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: Node: Unable to remove existing node_modules

Problem: Unable to remove existing local node_modules

Solution:

Run Command

cd path_with_modules
find . -name 'node_modules' -type d -prune -exec rm -rf '{}' +

Problem: Unable to remove all existing global node_modules

Solution:

Run Command

npm ls -gp --depth=0 | awk -F/ '/node_modules/ && !/\/npm$/ {print $NF}' | xargs npm -g rm

Problem: Python: Unable to remove existing python packages

Problem: Unable remove existing python packages

Solution: Run from elevated command prompt to removes all local packages in your environment

pip freeze | xargs pip uninstall -y

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
  1. Change the password:
passwd username
  1. Type:
exit
  1. Type:
wsl
  1. Confirm the new password works:
sudo echo hi
spark.conf.set("spark.databricks.pyspark.enablePy4JSecurity", "false")

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: DAVT_OD_NHANES_DEV_AZURE_CLIENT_SECRET

Error: Databricks: Spark: Cannot find catalog plugin class for catalog "spark_catalog": org.apache.spark.sql.delta.catalog.DeltaCatalog

Problem: org.apache.spark.SparkException: Cannot find catalog plugin class for catalog "spark_catalog": org.apache.spark.sql.delta.catalog.DeltaCatalog

Resolution:

From your virtual environment. You can select using workon venv_name

Run

pyspark --packages io.delta:delta-core_2.12:1.0.0 --conf "spark.sql.extensions=io.delta.sql.DeltaSparkSessionExtension" --conf "spark.sql.catalog.spark_catalog=org.apache.spark.sql.delta.catalog.DeltaCatalog"

or

Copy io.delta:delta-core_2.12:1.0.0 JAR file to $SPARK_HOME/lib and restart

This should make error go away.

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: Databricks: Spark: Illegal character in path

Problem: Spark illegal character in path

Resolution:
