Apache Hadoop

TuxCare's Endless Lifecycle Support (ELS) for Apache Hadoop provides security patches and selected bug fixes that are integral to the stable operation of applications running on these versions of Apache Hadoop core components. These components have either reached their end of standard support from vendors or have reached End of Life (EOL). Our ELS for Apache Hadoop service is designed to provide solutions for organizations that are not yet ready to migrate to newer versions and that are seeking long-term stability for their legacy Apache Hadoop applications.

Supported Versions

Apache Hadoop 2.7.1, 2.7.3

Installation

Prerequisites

Nexus repository access credentials (username and password) — contact sales@tuxcare.com
To browse available artifacts, visit TuxCare Nexus and click Sign in in the top right corner. You may need to refresh the page after logging in.

Navigate to the build tool directory

Windows

Maven: C:\Users\{username}\.m2
Gradle: C:\Users\{username}\.gradle

macOS

Maven: /Users/{username}/.m2
Gradle: /Users/{username}/.gradle

Linux

Maven: /home/{username}/.m2
Gradle: /home/{username}/.gradle

Configure credentials

For Maven, you may choose any valid <id> value instead of tuxcare-registry, but the same value must be used in both settings.xml and pom.xml.

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0">
    <servers>
        <server>
          <id>tuxcare-registry</id>
          <username>USERNAME</username>
          <password>PASSWORD</password>
        </server>
    </servers>
</settings>

Here USERNAME and PASSWORD are your TuxCare credentials.

Add the TuxCare repository
Add the TuxCare Apache Hadoop repository and plugins to your build configuration.
```
<repositories>
  <repository>
      <id>tuxcare-registry</id>
      <url>https://nexus.repo.tuxcare.com/repository/els_java/</url>
  </repository>
</repositories>
```
- To fully switch from the official Apache Hadoop repository, replace it with the TuxCare repository.
- To keep both, add TuxCare after the official one.
Example Maven and Gradle projects are available on GitHub. Remember to set the required environment variables.
- Maven
- Gradle

Update dependencies

Replace Apache Hadoop dependencies with TuxCare-maintained versions. You can find artifact versions on Nexus — sign in with your TuxCare credentials.

Verify the setup
Use your build tool to list the project's dependencies and confirm TuxCare packages are resolved correctly.
```
mvn dependency:tree -Dverbose
```
Build the project
Include any library from the repository and run a build.
```
mvn clean install
```
The build tool you're using should be able to identify and resolve dependencies from the TuxCare ELS for Apache Hadoop repository.
