Chesnay Schepler commented on FLINK-11162:
------------------------------------------
As of right now this cannot be done properly since the backing data-structure
(the ExecutionGraph) is minimally aware of operators. Literally the only thing
it knows about is the operator IDs contained in a given task, and this only
applies to streaming jobs. It is neither aware of their names, or can it make
any assumptions about the ID order.
Implementing this in a way that is not a band-aid/hack requires significantly
more changes to the ExecutionGraph, and I don't think we're really willing to
do this right now.
> Provide a rest API to list all logical operators

> Key: FLINK-11162
> URL: https://issues.apache.org/jira/browse/FLINK-11162
> Project: Flink
> Issue Type: New Feature
> Components: REST
> Reporter: vinoyang
> Assignee: lining
> Priority: Major
>
> The scene of this issue:
> We are using the indicator variable of the operator: <operator_id>,
> <operator_name>.
> We have customized the display of the indicator. Based on the query purpose,
> we currently lack an interface to get all the logical operators of a job. The
> current rest API only provides the chained node information.
