Chesnay Schepler commented on FLINK-1418:
-----------------------------------------
is this not doable without breaking programs?
I'm thinking of something like this:
whenever a print sink is created, an accumulator is created that stores the
output. the name of the accumulator is stored in a list in the ExEnv.
within env.execute(), after everything else ran (as in, before we return the
JobExecutionResult), iterate through the accumulator entries stored and print
the outputs the contents.
> Make 'print()' output on the client command line, rather than on the task
> manager sysout

> Right now, the {{print()}} command prints inside the data sinks where the
> code runs. It should pull data back to the client and print it there.
