MacOS Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
I solved this error. I build the source code(hadoop-3.0.0-src.tar.gz).Then i copy hadoop-3.0.0-src/hadoop-dist/target/hadoop-3.0.0/lib/native to ${HADOOP_HOME}/lib/native/
I write an article for build Hadoop source code for macOShttps://medium.com/@zekexu/build-hadoop-source-code-on-macos-3f932780fd84Hope helpful to you
