I was following https://amodernstory.com/2014/09/23/installing-hadoop-on-mac-osx-yosemite/ to install hadoop on my mac for local small tasks.
When hstart/hstop, getting "WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable"
Have tried options in below link to rename folder/path for lib/native. Renamed libexec/ to lib/ but errors in scripts that libexec should be correct.
Hadoop "Unable to load native-hadoop library for your platform" warning
However, in hadoop 3.0.0, the structure is like:
username-local:hadoop me$ pwd
/usr/local/Cellar/hadoop
username-local:hadoop me$ ls
3.0.0 hdfs
username-local:hadoop me$ cd 3.0.0/
username-local:3.0.0 me$ ls
INSTALL_RECEIPT.json NOTICE.txt bin sbin
LICENSE.txt README.txt libexec
username-local:3.0.0 me$ cd libexec/
username-local:libexec me$ ls
bin etc libexec logs sbin share
username-local:libexec me$ cd libexec/
username-local:libexec me$ pwd
/usr/local/Cellar/hadoop/3.0.0/libexec/libexec
username-local:libexec me$ ls
hadoop-config.sh hdfs-config.sh tools

Any ideas please? Thank you.
