> We are using 0.10.2.0 (but this is reproducible even with 0.10.2.1 and latest
> upstream) in our environments. Our topic names contain (one or more) dot
> characters in their name. So we have topics like {{foo.bar-testtopic}}. Topic
> deletion is enabled on the broker(s) and our application does delete the
> topics as and when necessary.
> We just ran into a case today where for some reason the Kafka broker had
> either to be taken down (or went down on its own). Some of the topics which
> were deleted (i.e. a deletion marker folder was created for them) were left
> around after Kafka broker had gone down. So the Kafka logs dir had
> directories like
> {{foo.bar-testtopic-0.bb7981c216b845648edfe6e2b0a5c050-delete}}.
> When we restarted the Kafka broker, it refused to start and kept shutting
> down and running into this exception:
> {code}

> The only way we could get past this is pointing Kafka broker to a different
> Kafka logs directory which effectively meant a lot our topics were no longer
> accessible to the application.
