--------------------------------
Summary: Tez UI Vertex 404
Key: TEZ-3488
URL: https://issues.apache.org/jira/browse/TEZ-3488
Project: Apache Tez
Issue Type: Bug
Affects Versions: 0.8.4
Reporter: George Liaw
When we're trying to view vertices for a running job, the Vertex page will show
a 404 error saying:
"Could not retrieve expected data from @ <url>"
And the Vertex Counter page will show:
"Counters unavailable"
and
"Error code: Unknown, message: Resource Manager (RM) out of reach. Either it's
down or CORS is not enabled"
The RMs are up and CORS is enabled. If we go to the displayed url, we get the
expected XML with the application info. When the DAG finishes running, those
errors go away and the pages display fine. Any idea what's going on here?
