Test-Hadoop

The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures.

There are two ways to install Hadoop, i.e. Single node and Multi node.

Single node cluster means only one DataNode running and setting up all the NameNode, DataNode, ResourceManager and NodeManager on a single machine. This is used for studying and testing purposes. For example, let us consider a sample data set inside a healthcare industry. So, for testing whether the Oozie jobs have scheduled all the processes like collecting,

PPPoE refers to Point-to-Point Protocol over Ethernet is a network protocol for encapsulating PPP frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet.

In Ubuntu 20.04LTS I have found that in setting>network you just cant setup a new connection of dsl/ppoe type (I don't know why!) So you can use nmcli(network managerment command line)!

• Name DSL/PPPoE connection : nmcli con edit type pppoe con-name "Your DSL name"

• IPS provided username : set pppoe.username your_username
