----------------------------------

             Summary: Create printf/pretty-printer style output format
                 Key: GIRAPH-253
                 URL: https://issues.apache.org/jira/browse/GIRAPH-253
             Project: Giraph
          Issue Type: Bug
            Reporter: Jakob Homan


It would be nice to have an outputformat where the user could specify (from the command-line
in bin/giraph) the output of each vertex.  Something like:
{noformat}--pretty-print="Hello, my name is %id and my value is %value. I have %edges.count
edges"{noformat}
This would result in text files, each line of which would correspond to a vertex.
This would make it very easy for people to spit out different output formats without having
to actually write any code...

Bonus points: only print the line if some predicate holds true --pretty-print-if="edges.count>10"
