This sounds like https://issues.apache.org/jira/browse/KAFKA-5232. It’s been fixed a few days back in upstream and will be available in next releases.
Having said that, you note something about split() method which wasn’t applicable here. Which version of Kafka are you on? Can you paste the complete exception stacktrace that you are running into? -Jaikiran On 19-May-2017, at 7:57 PM, Apache Jenkins Server <jenk...@builds.apache.org> wrote: Hello, I have no idea how to submit a bug : amongst all the help given to participate to the project, submitting a bug is the hardest and least documented, neither is easy to do. So I hope this email will reach the proper hands on your side :-) The bug is easy to reproduce: 1 - Create a topic with dots inside the name (eg: test.test2.test3) 2 - Mark the topic for deletion 3 - Stop the server (using the stop service kafka command, which is an ugly kill -9 in behind...) 4 - Restart the server: it will say that it cannot find the topic to delete, because it seems to look for an extension but instead finds a topic name part. This is a simble mistake: the string is splitted on the dots, and instead of taking the last element of the list returned by the split() it seems to look for the first element + 1 (hence thinking topic is test and its extension is test2.test3.log). So the server crashes and is impossible to restore/restart until you perform a manual deletion. A fix and a cleaner shutdown method which will prevent creating "corrupted index files" is welcomed :-D Thank awesome guys Have a good day -- Fabien KERBOUCI M. +33 (0) 6 75 45 56 62 | T. +33 (0) 1 85 08 88 83 6, rue Antonin Raynaud - 92300 Levallois-Perret fkerbo...@opensense.fr | www.opensense.fr
