[IPython-dev] pyspark and IPython
Thu Aug 29 17:15:29 CDT 2013
Yes, ok I wasn't clear either. Meta thing - IPython and NB have spoilt me
- I want IPy as a cmd line for everything - and be able to launch all
cmdline programs from IPy and IPyNB. So that's the meta goal. Every new
cmdline I encounter I try to see if !ls works if not it is not a good
enough cmdline any more and I try to see if there is a cell magic for that
cmdline :-) !
In the context of Spark/Shark and family, they are early efforts and I want
to be able to play with the many moving parts in there fast and furiously,
without being limited by the earliness of their interface. So if I can
plug these into IPy then all the better.
I am not sure if there's any value in integrating the two parallel
computing models as they seem to serve different audiences. The IPy
parallel computing model seems closer to what the scientific community
needs and at first sight the Spark/Shark model seems to serve the more
business oriented data demographic.
Where there is an intersection is IMHO, in the ML area - we will learn
about that tomorrow in the conference. In any case in the spirit of "IPy
over everything" I'd like to hope I can do some integration.
Also Fernando is here too and we chatted at lunch but pretty much about
everything else except the AMP stuff. I think it makes more sense to wait
till the end of day tomorrow to report on the content.
P.S. In an IETF meetings decades ago Vint Cerf wore a t-shirt that said "IP
over everything", so "IPy over everything" is my homage to that t-shirt.
