-----------------------------------
Summary: Yarn single-job JobManagers should not allow uploads of
new jobs.
Key: FLINK-6455
URL: https://issues.apache.org/jira/browse/FLINK-6455
Project: Flink
Issue Type: Bug
Components: Webfrontend, YARN
Affects Versions: 1.2.1
Reporter: Stephan Ewen
Priority: Critical
When running a job on Yarn in the 'single job cluster' mode, the web UI must
not show the 'upload new job' option.
If users actually submit another job via the web UI, the JobManager starts
sharing the yarn cluster between these two jobs and there will be competition
for TaskManagers between the jobs.
