Work Description: mxm commented on issue #6426: [BEAM-3089] Fix default
values in FlinkPipelineOptions / Add tests
URL: https://github.com/apache/beam/pull/6426#issuecomment-422906216
@tweise As far as I see we have all the checkpointing related options
already exposed. The problem is indeed that there might be more options that
users want to configure. It could make sense to expose an interface to
configure all Flink options.

> Issue with setting the parallelism at client level using Flink runner
> ---------------------------------------------------------------------
>
> Key: BEAM-3089
> URL: https://issues.apache.org/jira/browse/BEAM-3089
> Project: Beam
> Issue Type: Bug
> Components: runner-flink
> Affects Versions: 2.0.0
> Environment: I am using Flink 1.2.1 running on Docker, with Task
> Managers distributed across different VMs as part of a Docker Swarm.
> Reporter: Thalita Vergilio
> Assignee: Grzegorz KoĊakowski
> Priority: Major
> Labels: docker, flink, parallel-deployment
> Fix For: 2.8.0
>
> Attachments: flink-ui-parallelism.png
>
> Time Spent: 3h
> Remaining Estimate: 0h
>
> When uploading an Apache Beam application using the Flink Web UI, the
> parallelism set at job submission doesn't get picked up. The same happens
> when submitting a job using the Flink CLI.
> In both cases, the parallelism ends up defaulting to 1.
> When I set the parallelism programmatically within the Apache Beam code, it
> works: {{flinkPipelineOptions.setParallelism(4);}}
> I suspect the root of the problem may be in the
> org.apache.beam.runners.flink.DefaultParallelismFactory class, as it checks
> for Flink's GlobalConfiguration, which may not pick up runtime values passed
> to Flink, then defaults to 1 if it doesn't find anything.
> Any ideas on how this could be fixed or worked around? I need to be able to
> change the parallelism dynamically, so the programmatic approach won't really
> work for me, nor will setting the Flink configuration at system level.
