Scott Kidder created FLINK-5648:
-----------------------------------
Summary: Task Manager ID missing from logs link in Job Manager UI
Key: FLINK-5648
URL: https://issues.apache.org/jira/browse/FLINK-5648
Project: Flink
Issue Type: Bug
Components: JobManager
Affects Versions: 1.2.0
Reporter: Scott Kidder
This appears to be a regression introduced in Flink 1.2.0 rc2. I've been using
1.2.0 rc0 without this issue being present.
The link from the Job Manager to download logs for a specific Task Manager
instance does not include the ID of the Task Manager. The following screenshot
shows the link:

The following exception appears in the Job Manager logs after trying to
retrieve the logs for a Task Manager (without the ID of the Task Manager given):
