@Xiang Fu, thanks - I checked and plugins.dir is set to /opt/pinot/plugins and classpath is set to /opt/pinot/lib/* but it seems to be fine. I see, for example that it's using gcsfs (creating files on gcs) and that it is ingesting using confluent avro plugin, also did

jmap -histo ...

and I see that the plugin classes are loaded. So can that error be ignored then?

then it could be something else

I observed similar logs for jetty server , seems to be ignorable.

@Xiang Fu I think there may have been an issue actually, was able to fix it, will create pr, lmk what you think.

When you have a chance:) I will add you as reviewer

please
