We had in the past the situation described in this link use-case-deleting-corrupted-kafka-topic
The situation repeated a little bit different this time. Taking a look on the list of topics, there were three topics marked for deletion.
None of them had a Leader or Isr, so after a little bit of investigation the conclusion that they weren’t available anymore on the filesystem.
My assumption is that the cluster controller began the delete process but failed before sending a new metadata update to the zookeepers.
A restart of the cluster controller was performed in order to provide a new epoch, and after that, manual deletion of the “deletion request” and metadata from the zookeepers(you can find the commands in the above link).
On another list, everything looks good.
