Ufuk Celebi commented on FLINK-9832:
------------------------------------
I didn't look into the code, but is it possible to fix the utility that is
responsible for parsing the query parameter in the mean time? In general, it
should be possible as it works in 1.4.
> 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.
