Rion Williams commented on FLINK-38331:
---------------------------------------
I'd be interested in taking on this work.
Reviewing over [the related code for this
section|https://github.com/apache/flink/blob/master/flink-runtime-web/web-dashboard/src/app/components/dagre/components/node/node.component.ts],
it looks like we already have the identifier of the node present in the
component so I think it would just be a matter of exposing it within the UI.
A more general question would be if this should be an optional field or perhaps
simply a detail that is displayed when hovering over the node (as I'm not sure
it is _always_ as valuable as many of the other characteristics. This way it
wouldn't dramatically shift the known layout, but the hash could be accessed
with a hover.
I'm not sure who the SME is for this area, but happy to take on adding this
functionality.
