Hi, I’m not sure if this is intentional, but in some cases the metadata log file not available by the time the application runs.  
My app attempts to open the file soon after start up, and sometimes I get this error:

```auto
[tester::#EA7] Running tests for Stage #EA7 (Listing Partitions - List for a single partition)

[tester::#EA7] Looks like your program has terminated. A Kafka server is expected to be a long-running process.

```

If the intention is to write while starting the app, it may be helpful to mention that the file should be opened later. If this behavior is part of the challenge, then disregard this message : )

Thanks
