In this article we are integrating hadoop with LVM to provide custom elasticity to hadoop cluster. so that we can increase or decrease storage according to over requirement without affecting data.
for this demonstration i am creating a cluster locally with the help of virtual machine box with Red hat enterprise linux 8 as base os . For storage attaching the virtual storage of 10GB to the slave node.
In this article we will automate the process of LVM and partitioning in Linux with the help of python script program. I am using Red hat Enterprise Linux8 for this demonstration.
Logical volume management (LVM) is a form of storage virtualization that offers system administrators a more flexible approach to managing disk storage space than traditional partitioning. … The goal of LVM is to facilitate managing the sometimes conflicting storage needs of multiple end-users.
To create this we first have to create PV (physical volume) and make it available with VG (Volume group) and make it available for LVM to…
In this article I am gonna show u how to create a setup for custom access to sites with the help of basic networking principle’s such as routing table, route rules.
I am performing this practical in Red Hat Enterprise Linux 8.
A routing table is a set of rules, often viewed in table format, that is used to determine where data packets traveling over an Internet Protocol (IP) network will be directed. All IP-enabled devices, including routers and switches, use routing tables.
A basic routing table includes the following information:
Pokemon Go was developed and published by Niantic Inc., and grew to 500+ million downloads and 20+ million daily active users and beaten all the records at launch
Pokemon Go engineers never thought their user base would increase exponentially to surpass expectations within a short time. They were not ready for it, and the servers couldn’t handle this much traffic. also faced a severe challenge when it came to vertical and horizontal scaling because of the real-time activity by millions of users worldwide and Niantic was not prepared for this.
Luke Stone, said, that the original estimation before launch of…
