How to run script in Pyspark and drop into IPython shell when done?

问题

I want to run a spark script and drop into an IPython shell to interactively examine data.

Running both:

$ IPYTHON=1 pyspark --master local[2] myscript.py

and

$ IPYTHON=1 spark-submit --master local[2] myscript.py

both exit out of IPython once done.

This seems really simple, but can't find how to do it anywhere.

回答1:

If you launch the iPython shell with:

$ IPYTHON=1 pyspark --master local[2]

you can do:

 >>> %run myscript.py

and all variables will stay in the workspace. You can also debug step by step with:

>>> %run -d myscript.py

回答2:

Launch the IPython shell using IPYTHON=1 pyspark, then run execfile('/path/to/myscript.py'), that should run your script inside the shell and return back to it.
