Hi,
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.
Cheers
