Duo's Mac authorization plugin 1.1.0 supports macOS 10.13 (High Sierra) and all later macOS 10 versions, which includes: 11.0 (Big Sur) - first supported in 1.1.0 10.15 (Catalina). The Apple M1 chip with built-in Secure Enclave brings the same powerful security capabilities of iPhone to Mac — protecting your login password, automatically encrypting your data, and powering file-level encryption so you stay safe. And the Apple M1 chip keeps macOS secure while it's running, just as iOS has protected iPhone for years.

If you turn this on, you'll be alerted any time a new app wants to send or receive data. Click Firewall Options to see which apps have sent or received data, and which you've allowed or blocked.

1. Install homebrew and case
Open the MAC terminal and install the necessary package manager for OS Xhomebrewandhomebrew cask
The code is as follows:
$ ruby -e '$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)' $ brew install caskroom/cask/brew-cask
2. Install Java

Hadoop is written in Java, so you need to pre install Java 6 or later
The code is as follows:
$ brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup $ brew cask install java
Test for successful installation
The code is as follows:
$ java -version
3. Configure SSH

In order to ensure the security of remote management of Hadoop and Hadoop node users sharing, Hadoop needs to configure SSH protocol
First, select System Preferences > share > Open remote login service > allow all users to access
Generate the key pair and execute the following command
The code is as follows:
$ ssh-keygen -t rsa
After executing this command, the ID is generated in the. SSH folder in the current user directory_ RSA file, execute the following command:
The code is as follows:
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
Use the following command to test whether you can log in without a password
The code is as follows:
$ ssh localhost # Last login: Thu Mar 5 17:30:07 2015
4. Install Hadoop
The code is as follows:
$ brew install hadoop
Hadoop will be installed in the / usr / local / cell / Hadoop directory
4.1. Configure Hadoop Mac mini with keyboard.
Configure Hadoop- env.sh
Find Hadoop in the directory / usr / local / cell / Hadoop / 2.6.0 / libexec / etc / Hadoop- env.sh file

4.1. Configure Hadoop Mac mini with keyboard.
Configure Hadoop- env.sh
Find Hadoop in the directory / usr / local / cell / Hadoop / 2.6.0 / libexec / etc / Hadoop- env.sh file
Find one of the lines:
Mac Os 10.10 YosemiteThe code is as follows:
export HADOOP_OPTS='$HADOOP_OPTS -Djava.net.preferIPv4Stack=true'
It is amended as follows: Android studio for mac el capitan download.
The code is as follows:
Mac Os X Yosemite 10.10export HADOOP_OPTS='$HADOOP_OPTS -Djava.net.preferIPv4Stack=true -Djava.security.krb5.realm= -Djava.security.krb5.kdc='
Find the core in the directory / usr / local / cell / Hadoop / 2.6.0 / libexec / etc / Hadoop- site.xml
Mac os x leopard 10 5 update. The code is as follows:
  hadoop.tmp.dir /usr/local/Cellar/hadoop/hdfs/tmp A base for other temporary directories.   fs.default.name hdfs://localhost:9000  
Find mapred in the directory / usr / local / cell / Hadoop / 2.6.0 / libexec / etc / Hadoop- site.xml , add:
The code is as follows:
  mapred.job.tracker localhost:9010  
Find HDFS in the directory / usr / local / cell / Hadoop / 2.6.0 / libexec / etc / Hadoop- site.xml
The code is as follows:
  dfs.replication 1  
Before running the background program, you must format the newly installed HDFS and create an empty file system by creating a storage directory and initializing metadata. Execute the following command:
The code is as follows:
$Hadoop namenode – format ා generates a string similar to the following: predicted: use of this script to execute HDFS command is truncated. Instead use the HDFS command for it. 15 / 03 / 05 20:04:27 info namenode.NameNode : STARTUP_ MSG: /************************************************************ STARTUP_ MSG: Starting NameNode STARTUP_ MSG: host = Andrew-liudeMacBook- Pro.local/192 .168.1.100 STARTUP_ MSG: args = [-format] STARTUP_ MSG: version = 2.6.0… ා most startups are omitted in this book_ MSG: java = 1.6.0_ 65 ************************************************************ /************************************************************ SHUTDOWN_ MSG: Shutting down NameNode at Andrew-liudeMacBook- Pro.local/192 .168.1.100 ************************************************************/
4.2. Start background program
Mac Os X Yosemite DownloadIn the / usr / local / cell / Hadoop / 2.6.0/sbin directory, execute the following command
