Subject [jira] [Commented] (BEAM-1631) Flink runner: submit job to a Flink-on-YARN cluster
Date Wed, 12 Jul 2017 15:38:00 GMT


Aljoscha Krettek commented on BEAM-1631:

This only works for submitting to an already running Flink on YARN cluster, right?

Flink 1.4 will (if all goes according to plan) come with programatic APIs for submitting a
job to a YARN cluster without having to start anything previously. I think this will make
things a lot easier and I suggest to wait until that is available.

> As far as I understand, running Beam pipelines on a Flink cluster can be done in two
> * Run directly with a Flink runner, and specifying {{--flinkMaster}} pipeline option
via, say, {{mvn exec}}.
> * Produce a bundled JAR, and use {{bin/flink}} to submit the same pipeline.
> These two ways are equivalent, and work well on a standalone Flink cluster.
> Submitting to a Flink-on-YARN is more complicated. You can still produce a bundled JAR,
and use {{bin/flink -yid <applicationid>}} to submit such a job. However, that seems
impossible with a Flink runner directly.
> If so, we should add the ability to the Flink runner to submit a job to a Flink-on-YARN
cluster directly.
