Subject [jira] [Commented] (FLINK-2989) Job Cancel button doesn't work on Yarn
Date Tue, 10 Nov 2015 12:18:10 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2989?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14998474#comment-14998474
] 

Maximilian Michels commented on FLINK-2989:
-------------------------------------------

Should we allow both, GET and DELETE? Via DELETE we would support Rest-style API calls if
desired. For the cancel button we would use the GET interface to support YARN properly.

> The newly added Cancel button doesn't work on Yarn, when accessing via Yarn Web Application
proxy. It works fine when we're directly on the web monitor.
> The reason is Yarn doesn't allow DELETE requests to the AM yet. It should be enabled
in 2.8.0. [YARN-2031, YARN-2084.]
> A workaround for now can be to use a {{GET}} method instead of {{DELETE}}, but that breaks
the conventions of REST.
