Override external SDK container URLs for Dataflow by default in Java SDK so users don't need to manually specify --sdkHarnessContainerImageOverrides for Java cross-language pipelines using Python transforms.

Why would the user have to manually (or automatically) specify this?

@chamikaramj what do you think of this?

I think this is done. Users do not have to specify "sdkHarnessContainerImageOverrides" when using Java multi-language on Dataflow with released Beam.
