2. Modify the Host Name (so the node)The host file has been configured in the initial environment. All nodes must synchronize the host file. This step is omitted.
3. SSH connection (all nodes)The purpose is to log on from the master node to all nodes without entering a password.
4. Disable the firewall (all nodes)The firewall may cause various exceptions in Hadoop-related component communication.

I used cloudera Manager server to install and manage hadoop clusters. I heard that general enterprises use cloudera to install and manage hadoop. I also want to try it. I checked the data for a day and found that cloudera is very mature, in addition, the installation methods of pseudo do distributed and cloudera

I personally recommend that you try either method 1 or 2. You should first have a clear understanding of the hadoop architecture, built-in components, and configu
After the Cloudera Manager server and Agent are started, you can configure the CDH5 installation.You can then test the 7180 port of the master node through the browser (since the boot of the CM server takes some time, this may take a while to access), and the default user name and password are admin.making a local sourceDownload CDH to local http://archive-primary.cloudera.com/cdh5/parcels/5.3.4/first,Here are three things to
