[jira] [Commented] (FLINK-26808) [flink v1.14.2] Submit jobs via REST API not working after set web.submit.enable: false

["Tobias Hofer (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-26808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17696167#comment-17696167 ] 

Tobias Hofer commented on FLINK-26808:
--------------------------------------

The expectation is that Flink behaves as documented.

In [https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/config/] I can read the following:
{quote}{{{}web.submit.enable{}}}: Enables uploading and starting jobs through the Flink UI {_}(true by default){_}. Please note that even when this is disabled, session clusters still accept jobs through REST requests (HTTP calls). This flag only guards the feature to upload jobs in the UI.
{quote}
I would like to be able to disable submission via UI but still allow to job sumission to work.

This behavior impacts the Flink Kubernetes Operator. It fails with

{color:#174ea6}Warning | SESSIONJOBEXCEPTION | org.apache.flink.runtime.rest.util.RestClientException: [Not found: /v1/jars/upload]"{color}

> Greetings,
> I am using flink version 1.14.2 and after changing web.submit.enable to false, job submission via REST API is no longer working. 
> The app that uses flink receives a 404 with "Not found: /jars/upload" 
> Looking into [documentation|[https://nightlies.apache.org/flink/flink-docs-release-1.14/docs/deployment/config/]]  saw that web.upload.dir is only used if  {{web.submit.enable}} is true, if not it will be used JOB_MANAGER_WEB_TMPDIR_KEY
> Doing a curl to /jars it returns:
> {code:java}
> curl -X GET http://localhost:8081/jars
> HTTP/1.1 404 Not Found
> {"errors":["Unable to load requested file /jars."]} {code}
> Found this issue related to option web.submit.enable https://issues.apache.org/jira/browse/FLINK-13799
> Could you please let me know if this is an issue that you are already aware?
> Thanks in advance
> Best regards,
> Luís Costa
