I am looking into the problem of running jobs to generate statistics across
a large data set that would be split into different clusters
geographically. Each cluster would have a unique piece of the overall data
set, as the network overhead to collocate the data would be too much. I
tried searchin
You could easily write Cascading apps that could pull all the data into a
single source and perform the processing.
You could also use it to launch jobs in different clusters from a single
application (each Flow can be given unique properties causing it to run mr jobs
on arbitrary clusters).
