Hadoop Distributed File System
Hadoop Distributed File System (HDFS) is a distributed file system that is designed to store and manage large amounts of data across multiple machines in a Hadoop cluster.
HDFS is based on the Google File System (GFS) and is designed to provide high throughput and data access rates, even when dealing with large files. It is also fault-tolerant, meaning that it can detect and recover from hardware failures automatically.
The basic architecture of HDFS consists of a NameNode and multiple DataNodes. The NameNode is responsible for managing the file system namespace, and the DataNodes are responsible for storing and managing the actual data.
Files in HDFS are split into blocks of a fixed size (usually 128 MB), and each block is replicated across multiple DataNodes to ensure fault tolerance. The NameNode maintains a metadata image of the entire file system, including the location of each block of data.
HDFS is typically used in conjunction with other Hadoop components, such as MapReduce, to perform large-scale data processing and analysis.
linux how to Install the app Chrome using the locally downloaded .deb file and dpkg Start the application
To install Chrome using the locally downloaded .deb file and dpkg, follow these steps:
1. Open the terminal on your Linux system.
2. Navigate to the directory where the .deb file of Chrome is downloaded. For example, if the file is downloaded to the Downloads folder, run the following command:
```
cd ~/Downloads
```
3. Install the Chrome package using the dpkg command:
```
sudo dpkg -i google-chrome-stable_current_amd64.deb
```
Note: Replace "google-chrome-stable_current_amd64.deb" with the actual name of the Chrome package you have downloaded.
4. Once the installation is complete, you can start the Chrome application by typing the following command in the terminal:
```
google-chrome-stable
```
Alternatively, you can search for "Google Chrome" in the applications menu of your Linux system and launch it from there.
