I have make sure that no other okhttp3 version exists in the repo, and the only okhttp3 version I am using is 4.9.0 (which is introduced by influxdb-java). To avoid any possible conflict, I have shaded the okhttp3 path.

I am running the job in a spark environment, and I encountered the error shown below,
