Hello,
Since ExecutionEnvironment#execute() blocks until the job is finished
you should be able to just do this:
data.writeAsText();
env.execute();
{ do Map-Job }
Note that your current solution is wrong, as it translates to this:
DataSet result = ...
result.writeAsText();
if (result.count() > 0){ ... do Map-Job ... }

Hi,
I have a program that contains a preprocessing with Flink Objects and at the
end writes the result with „result.writeAsText(„...“)“.
After that I call a method that is basically a MapReduce-Job (actually only a
Map-Job) which depends on the written file.
So what is the smartest way to delay the execution of the Map-Job until the
file is written completely?
Right now I I am doing it the following way:
val written = result.writeAsText(„…“)
if(written.getDataSet.count() > 0){ ...do Map-Job...}
Thanks in advance!
Best regards,
Lydia
