Gary Yao created FLINK-8912: ------------------------------- Summary: 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, 1.6.0 Environment: commit: c531486288caf5241cdf7f0f00f087f3ce82239f Reporter: Gary Yao 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
