Description

It is hard to troubleshoot when all subtasks are always on the SCHEDULED status(just like the screenshot below) when users submit a job.

The most common reason for this problem is that vertex has applied for more resources than the cluster has. A pending slots tab could help users to check which vertex or subtask is blocked.

 

REST API needed:

add /jobs/:jobid/pending-slots API to get pending slots data.
