Hey Ismael, Thanks much for catching this! Sorry I didn't catch this issue before.
These files were uploaded by release.py scrip in the repo. kafka_2.12-2.1.0.mapping contains the following string and the other files are the signature and hash of the file kafka_2.12-2.1.0.mapping: /home/dolin/research/kafka/.release_work_dir/kafka/core/build/libs/kafka_2.12-2.1.0.jar /home/dolin/research/kafka/.release_work_dir/kafka/core/build/tmp/scala/compilerAnalysis/compileScala.analysis It is weird to have these files.. Let me generate another release candidate and try to fix this issue. Thanks, Dong
