Hello,
I am trying to submit multiple jobs to flink from within my Java program.
I am running into an exception that may be related:
java.io.OptionalDataException.
Should I be able to create multiple plans/jobs within a single session and
execute them concurrently?
If so, is there a working example you can point me at?
Do I share the same ExecutionEnvironment?
It looks like calls to getExecutionEnvironment() return the same one.
I have a number of different transformations on my data I'd like to make.
I'd rather not create one very large job and have them processed in
parallel.
My cluster has enough resources that performing each job sequentially would
be very wasteful.
Thank you,
David
