Re: [I] [Bug] readOffload NoClassDefFoundError [pulsar]

lhotari commented on issue #23736:
URL: https://github.com/apache/pulsar/issues/23736#issuecomment-6288124743

   Closing this issue. The likely cause is OS cleanup of `/tmp` (for example, by `systemd-tmpfiles`), which deletes extracted NAR files while the broker is running. The default `narExtractionDirectory` is `java.io.tmpdir`. See #24031 for the details.
   
   The solution is to set `narExtractionDirectory` (or `-Dnar.extraction.tmpdir` in `PULSAR_EXTRA_OPTS`) to a dedicated directory that isn't cleaned up automatically. This is now documented in:
   
   - #27011: the `narExtractionDirectory` descriptions in `broker.conf`, `standalone.conf`, `proxy.conf`, `functions_worker.yml` and the generated configuration reference
   - apache/pulsar-site#1258: a "Configure the NAR extraction directory" section for bare-metal installations
