How to Set Java Home for Notebook in SageMaker

Question

So it seems that I have Java installed after running the below line in the SageMaker Notebook Terminal:

bash-4.2$ sudo yum install java-1.8.0-openjdk 

In the terminal I write the following to confirm:

bash-4.2$ java -version 
java version "1.7.0_261" OpenJDK Runtime Environment (amzn-2.6.22.1.83.amzn1-x86_64 u261-b02) OpenJDK 64-Bit Server VM (build 24.261-b02, mixed mode)

In my notebook I have the following Lines of code:

import tabula

tabula.environment_info()

The notebook results in an error with:

java -version` faild. `java` command is not found from this Pythonprocess. Please ensure Java is installed and PATH is set for `java`

Yet, in the terminal I see this:

bash-4.2$ java -version 
java version "1.7.0_261" OpenJDK Runtime Environment (amzn-2.6.22.1.83.amzn1-x86_64 u261-b02) OpenJDK 64-Bit Server VM (build 24.261-b02, mixed mode)

I definitely have a java environment. How can I set my notebook to find this?

Adding Java to the system Path on your Notebook should resolve this. See How to fix this error on tabula.read_pdf() function in Python .

Despite running in AWS, you can often resolve issues in SageMaker Notebooks the same way you would resolve them on your local machine.
