------------------------------------
Affects Version/s: (was: 1.6.0)
> Web UI does not render error messages correctly in FLIP-6 mode
> --------------------------------------------------------------
>
> Key: FLINK-8912
> URL: https://issues.apache.org/jira/browse/FLINK-8912
> Project: Flink
> Issue Type: Bug
> Components: Webfrontend
> Affects Versions: 1.5.0
> Environment: commit: c531486288caf5241cdf7f0f00f087f3ce82239f
> Reporter: Gary Yao
> Assignee: Chesnay Schepler
> Priority: Critical
> Labels: flip6
> Fix For: 1.5.0
>
>
> *Description*
> The Web UI renders error messages returned by the REST API incorrectly, e.g.,
> on the job submission page. The JSON returned by the REST API is rendered as
> a whole. However, the UI should only render the contents of the {{errors}}
> field.
> *Steps to reproduce*
> Submit {{examples/streaming/SocketWindowWordCount.jar}} without specifying
> program arguments. Error message will be rendered as follows:
> {noformat}
> {"errors":["org.apache.flink.client.program.ProgramInvocationException: The
> program plan could not be fetched - the program aborted
> pre-maturely.\n\nSystem.err: (none)\n\nSystem.out: No port specified. Please
> run 'SocketWindowWordCount --hostname <hostname> --port <port>', where
> hostname (localhost by default) and port is the address of the text
> server\nTo start a simple text server, run 'netcat -l <port>' and type the
> input text into the command line\n"]}
> {noformat}
> Note that flip6 mode must be enabled.
