Accessing Environmental Variables from Projects
This topic shows you how to access environmental variables from your code.
Environmental variables are injected into every engine launched for a project, contingent on the scope at which the variable was set (global, project, etc.). The following code samples show how to access a sample environment variable called DATABASE_PASSWORD from your project code.
R
database.password <- Sys.getenv("DATABASE_PASSWORD")
Python
import os
database_password = os.environ["DATABASE_PASSWORD"]
Scala
System.getenv("DATABASE_PASSWORD")
Appending Values to Environment Variables:
You can also set environment variables to append to existing values
instead of replacing them. For example, when setting the
LD_LIBRARY_PATH
variable, you can set the value to
LD_LIBRARY_PATH:/path/to/set
.
