Updating java in ubuntu
It is a very modern desktop environment with a powerful search tool for finding all of your applications and documents and it integrates well with common applications such as audio players, video players, and social media.There are other desktop environments available within the package manager including GNOME, LXDE, XFCE, KDE, and MATE.So, in this post I am going to consider three machines (One as Master Node and rest two are as Slave Nodes) for setting up Hadoop Cluster.Here there is a correlation between number of computer in cluster with size of data and data processing technique.
The latest Long Term Support Release - 18.04 - will be supported until April 2023 and is the version that is better for people who don't like to upgrade their operating system regularly.
The Unity Desktop isn't as customizable as many other Linux desktop environments are but you can do basic things like changing the wallpaper and determine whether the menus appear as part of the application or in the top panel.
Say thanks to Ondřej Surý for maintaining PPA of most the popular PHP versions on launchpad.
