azkaban web /stats url doesn't work

[wyukawa]

If I access to /stats, the following error occurs.

Hey @wyukawa ! Thanks for reporting.
What are the steps to reproduce this?

[wyukawa]

If you access http://localhost:8081/stats, you can confirm.

/stats endpoint is the following.
https://github.com/azkaban/azkaban/blob/master/azkaban-web-server/src/main/java/azkaban/webapp/AzkabanWebServer.java#L810

I assume this is when you bring up the solo-server. correct?

[wyukawa]

No, I confirm at azkaban-web and azkaban-executor mode.

If I check log after adding #890, there is the following stacktrace.

[armisael]

Did you set executor.metric.reports=true (and executor.metric.milisecinterval.default) in your azkaban.properties as stated in the documentation?

[wyukawa]

ah, I see. Thanks!
