> Web UI shows "User Configuration" preserving lines and whitespaces
> ------------------------------------------------------------------
>
> Key: FLINK-31110
> URL: https://issues.apache.org/jira/browse/FLINK-31110
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Web Frontend
> Affects Versions: 1.16.1
> Reporter: Mingliang Liu
> Priority: Minor
> Labels: pull-request-available
>
> Currently one can use \{{env.getConfig().setGlobalJobParameters(...)}} for
> setting user configurations. It will also show up in the Web UI > Running
> Jobs > Job Configuration > User Configuration section. This is nice so users
> can confirm the user configuration (key/value pair) gets populated.
> However, it prints the plain string which does not work well with values that
> contains whitespaces and line breaks. For example, we have some prettified
> JSON configuration and sometimes formatted SQL statements in those
> configurations, and it's showing in a compacted HTML format - not human
> readable.
> I propose we keep the whitespaces and lines for this "User Configuration"
> section in the Web UI. The implementation can be as simple as adding
> {{style="white-space: pre-wrap;"}} to the rows in that section.
