Apache Flink 1.9.2 Docker image shows no web interface / blank page for job manager

Kaymak, Tobias
Hello,

I am trying out the Flink Docker image 1.9.2 (1.9.1 works) - but the Jobmanager shows just a blank page when accessing it's webinterface on port 8081.

I enabled DEBUG/TRACE logging and it looks ok to me when I make the request:

I tried Chrome (newest version) and Safari, both with Incognito modes as well. The webserver returns Javascript and HTML to the browser - so I am very puzzled about what could be wrong here?

Re: Apache Flink 1.9.2 Docker image shows no web interface / blank page for job manager

Rasik Sheth
This usually happens when Content-Type: text/html; is missing in response headers. can you check if it is there.

Re: Apache Flink 1.9.2 Docker image shows no web interface / blank page for job manager

Yang Wang
I use the following command to have a test on my Mac.
It seems to work pretty well. The webui could be shown normally.

$ docker run -d -p 8081:8081 flink:1.9.2-scala_2.11 jobmanager


So could you inspect in Chrome and check whether all the resources
could be loaded successfully?


Best,
Yang

Re: Apache Flink 1.9.2 Docker image shows no web interface / blank page for job manager

Kaymak, Tobias
Hello,

this seems to be related to an open issue with Apache Beam's 2.19.0 compatibility with Flink 1.9.2 and not directly related to Apache Flink.

Have a nice day :)

Best,
Tobias
