How to use Oozie action with input path depending on flag

I have an oozie action that has a defined input path. In case this path does not exist I want to set the input to some default path.

Is there a way to have the path depending on a condition? I know I can replicate the action for each possible input and have a condition that routes to the correct action. However, this is not scalable when having many conditional paths.

Solution

  • Oozie allows you to use EL expressions, which includes the conditional operator ?:. This makes it fairly straight-forward to implement a default path when the specified path does not exist:

    ${fs:exists(specified_path) ? specified_path : default_path}
