-Keeping intermediate results
Yaron Gonen 2011-11-06, 16:21
Suppose I have chained M/R jobs that traverse a graph and look for nodes
with a specific value. Every time a Map encounters that value, I'd like to
keep that node in the final result.
I can of course save it with a special key and use a condition in the
Reducer, but is there a more formal or elegant way?
