Aljoscha Krettek commented on BEAM-1107:
----------------------------------------
Yep, you're right but even in the black text the operation names (MapPartition,
GroupCombine and so on) are hardcoded in Flink right now so we cannot change
that coming from Beam-on-Flink. Changing that would require changes to Flink
(which I'm not opposed to).
> Display user names for steps in the Flink Web UI

> [copying in-person / email discussion at Strata Singapore to JIRA]
> The FlinkBatchTransformTranslators use transform.getName() [1] -- this is the
> "SDK name" for the transform.
> The "user name" for the transform is not available here, it is in fact on the
> TransformHierarchy.Node as node.getFullName() [2].
> getFullName() is used some in Flink, but not when setting step names.
> I drafted a quick commit that sort of propagates the user names to the web UI
> (but only for DataSource, and still too verbose:
> https://github.com/dhalperi/incubator-beam/commit/a2f1fb06b22a85ec738e4f2a604c9a129891916c)
> Before this change, the "ReadLines" step showed up as: "DataSource (at
> Read(CompressedSource)
> (org.apache.beam.runners.flink.translation.wrappers.SourceInputFormat))"
> With this change, it shows up as "DataSource (at ReadLines/Read
> (org.apache.beam.runners.flink.translation.wrappers.SourceInputFormat))"
> which I think is closer. [I'd still like it to JUST be "ReadLines/Read" e.g.].
> Thoughts?
