问题
Is it possible to install python packages in a Google Dataproc cluster after the cluster is created and running?
I tried to use "pip install xxxxxxx" in the master command line but it does not seem to work.
Google's Dataproc documentation does not mention this situation.
回答1:
This is generally not possible after cluster is created. I recommend using an initialization action to do this.
As you've noticed, pip is also not available by default. So you'll want to run easy_install pip followed by pip install command.
Finally, if your intention is to use this cluster in any automation, and/or you want hermeticness, I recommend creating a wheel that you store in GCS and download in init action. You'd then install your wheel. Wheels have added benefit of being faster than installing many packages from pip directly.
