Mac configuration Hadoop pseudo-distributed environment

The overall configuration process refers to this blog , but an error occurs when the namenode is initialized JAVA_HOME @@HOMEBREW_JAVA@@ does not exist.. By consulting another blog, I found that the JAVA_HOME in the hadoop-env.sh file was not configured correctly. Add the configuration of JAVA_HOME to the file, and no error will be reported.
