Hi Dave,
In batch mode an operator/task only starts running once all input tasks are
finished. So without further detail this is perfectly in line with what you
describe.

Subject: Re: Flink operator stuck on created
I should note - this job is being run in batch mode. Could there be a deadlock
related to FLINK-16430?

Hi,
I have a Flink job on EMR with an operator stuck on CREATED. The subtasks are
not being assigned to task manager slots. The previous operator is running and
has non-zero Bytes Sent and Records Sent. When the job started the Job manager
requested new workers to start a bunch of the operators but it's not requesting
any more so the available slots is 0 and the job just seems to have stalled.
Any pointers on what I might be doing wrong?
I'm specifying parallelism 24 and that's how many task slots are being
requested by the job manager but also how many subtasks are being created each
operator. Should I (if so how) specify these two numbers separately?
Thanks,
Dave
