How to write flink job output to a single location instead of two locations

Currently, I have Flink operating as a cluster through Docker, employing three containers: one for the jobmanager and two for the taskmanagers. Whenever I submit a job, the job's output gets written to both containers. I am interested in finding a solution to consolidate the output in a single location, preferably either on the local machine. Is there a way to achieve this?

Solution

You could:

use a single task manager with 2x as many slots (you'll still end up with multiple files, but they'll be in the same directory on the same machine)
reduce the parallelism of the job
reduce the parallelism of the sink
