This article is about how to install CDH5.4.0 in Impala. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Impala is a real-time query open source project released by Cloudra, which is based on Hive but can be calculated in memory. It is the preferred PB-level big data real-time query analysis engine using CDH.

There are two ways to install Impala, CM and manual installation. Manual installation is troublesome and requires additional steps to verify the interaction with other components. Here, CM is used to install.

0. Expand the VM virtual machine space

Originally, 10G of hard disk space was allocated to the virtual machine to install and test the framework related to Hadoop, but after downloading CDH, it suddenly felt that 10G of space was so small that it needed to be expanded.

A. Select the CVM to be expanded-- > Virtual Machine-- > Settings-- > hard disk (SCSI)-- > Utility-- > expand

B. Log in to the virtual machine to view the current situation

[root@nnode ~] # df-hFilesystem Size Used Avail Use% Mounted on/dev/sda2 8.6G 5.1G 3.1G 63% / tmpfs 935M 0935M 0% / dev/shm/dev/sda1 291M 39M 238M 14% / boot.host:/ 146G 79G 68G 54% / mnt/hgfs # this is my shared directory [root@nnode ~] #

C. Create a partition

1. Installation preparation

The latest version of CM is 5.5.1, where CM5.4.0 and CDH5.4.0 are installed.

Download links to CM and CDH can be found on this site, and when the appropriate version is selected, there will be help for installation.

Online installation and offline installation can be used to install CM. Online installation also requires downloading the basic installation package locally and then installing it. The installation process automatically downloads the software that needs to be installed, but the bandwidth requirement is high. As the domestic network environment is easy to be limited when downloading overseas resources, which affects the installation speed, you can install it by configuring the yum source locally.
