Installation environment: the system is CentOS7,64 bit, all the software installation process needs to adapt to this system.
Use linux command to view its own operating system:
Note: If you install CentOS7 on a virtual machine, use the minimal installation, start the CM may pstree may report errors found.
[root@master ~]# uname -a
Linux master 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Note: this article if copied directly linux command executed easily lead to unusable.
Overall grasp: for all nodes: unzip cm to the / opt directory, decompression will generate two directories
1、cloudera
2、cm-5.8.2
There are two empty directory csd cloudera and parcel-repo directory under which the parcel-repo is used to store Parcels (three) file
Or may be only on the master decompression and scp to other nodes.
Therefore, the need to manually install Master CM and parels (three files), but only need to install slave CM, automatically copied parces other documents to the slave node during the initialization of CDH.
