Chesnay Schepler commented on FLINK-9832:
-----------------------------------------
I wanted to do this for 1.7.
To properly implement this (i.e. also adjust the WebUI to use this feature) in
1.5/1.6 we'd also have to touch legacy handlers which IIRC still don't have
access to the post body content. Unless we introduce a legacy mode flag to the
UI, but I wanted to avoid stuff like that for now...
> Allow commas in job submission query params
> -------------------------------------------
>
> Key: FLINK-9832
> URL: https://issues.apache.org/jira/browse/FLINK-9832
> Project: Flink
> Issue Type: Bug
> Components: REST
> Affects Versions: 1.5.1
> Reporter: Ufuk Celebi
> Priority: Minor
>
> As reported on the user mailing list in the thread "Run programs w/ params
> including comma via REST api" [1], submitting a job with mainArgs that
> include a comma results in an exception.
> To reproduce submit a job with the following mainArgs:
> {code}
> --servers 10.100.98.9:9092,10.100.98.237:9092
> {code}
> The request fails with
> {code}
> Expected only one value [--servers 10.100.98.9:9092, 10.100.98.237:9092].
> {code}
> As a work around, users have to use a different delimiter such as {{;}}.
> The proper fix of this API would make these params part of the {{POST}}
> request instead of relying on query params (as noted in FLINK-9499). I think
> it's still valuable to fix this as part of a bug fix release for 1.5.
