> [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?
