This is not problem directly caused by Spark, but it's related; thus asking here. I use spark to read data from parquet and processing some http call with sttp (https://github.com/softwaremill/sttp). However, spark throws
Caused by: java.io.NotSerializableException: com.softwaremill.sttp.FollowRedirectsBackend It's understood why such exception is thrown because FollowRedirectsBackend is not seralizable. So I would like know in such case - are there any ways to get around this problem without modifying, recompiling original code? Thanks
