Subject [jira] [Created] (FLINK-5648) Task Manager ID missing from logs link in Job Manager UI
Date Wed, 25 Jan 2017 23:53:26 GMT
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):
