Semantic Coherence: Apache Ranger – Signal Evidence & AI Readability

Apache Ranger™ is a framework to enable, monitor and manage comprehensive data security across the Hadoop platform.
The vision with Ranger is to provide comprehensive security across the Apache Hadoop ecosystem. With the advent of Apache YARN, the Hadoop platform can now support a true data lake architecture. Enterprises can potentially run multiple workloads, in a multi tenant environment. Data security within Hadoop needs to evolve to support multiple use cases for data access, while also providing a framework for central administration of security policies and monitoring of user access.
Please read the FAQs if you need to understand how it works over Apache Hadoop components.

[H3] Goals Overview
Apache Ranger has the following goals:
Centralized security administration to manage all security related tasks in a central UI or using REST APIs.
Fine grained authorization to do a specific action and/or operation with Hadoop component/tool and managed through a central administration tool
Standardize authorization method across all Hadoop components.
Enhanced support for different authorization methods - Role based access control, attribute based access control etc.
Centralize auditing of user access and administrative actions (security related) within all the components of Hadoop.

[H3] Bring up Apache Ranger in minutes using Docker ...
Please follow the instruction provided at Wiki Page for Running Apache Ranger

[H3] Build Process
1. Check out the code from GIT repository

git clone https://gitbox.apache.org/repos/asf/ranger.git

cd ranger

Alternatively, you can checkout the code from github:

git clone https://github.com/apache/ranger

cd ranger

2. Please execute the following Maven command:

$ export JAVA_HOME=%jdk 7 Home%

$ mvn -Pall clean

$ mvn -Pall -DskipTests=false clean compile package install

3. After the above build command execution, you should see the following TAR files in the target folder:
ranger-%version-number%-%module-name%.tar.gz

[H3] Create an Apache Release
1. Checkout from ranger release branch

$ git checkout ranger-%version%

2. Run maven commands to build and validate the build is working fine (See Build Process: step 2):

$ export JAVA_HOME=%jdk 7 Home%

$ mvn -Pall clean

$ mvn -Pall -DskipTests=false clean compile package install

3. Clean all generated files for building the source build
$ mvn -Pall clean

4. Create a TAR source file using the following command:
$ ant -f release-build.xml -Dranger-release-version=%version-number%

5. Now, the following files are ready to be published for release:
./target/apache-ranger-%version-number%.tar.gz
./target/apache-ranger-%version-number%.tar.gz.asc
./target/apache-ranger-%version-number%.tar.gz.mds

[H3] Verifying Build (also called as a Release)
1. Download the release source file, apache-ranger-%version-number%.tar.gz (from URL provided in the release email)
2. Download the PGP signature for, apache-ranger-%version-number%.tar.gz which usaully named as apache-ranger-%version-number%.tar.gz.asc (from URL provided in the release email)
3. Get the keys used to sign the releases for verification. https://dist.apache.org/repos/dist/release/ranger/KEYS

$ gpg --import KEYS
$ gpg --fingerprint key-id

4. Execute the following command to verify the release
$ gpg --verify apache-ranger-%version-number%.tar.gz.asc apache-ranger-%version-number%.tar.gz
5. Download MD5/SHA hash for apache-ranger-%version-number%.tar.gz which usaully named as apache-ranger-%version-number%.tar.gz.mds (from URL provided in the release email)
$ gpg --print-mds apache-ranger-%version-number%.tar.gz
Compare MD5, SHA hash generated from the above command and the signature available in the apache-ranger-%version-number%.tar.gz.mds.

[H3] Importing Apache Ranger Project into Eclipse

1. Create a Eclipse workspace called 'ranger'

2. Import maven project from the root directory where ranger source code is downloaded and build using the following command:

$ export JAVA_HOME=%Jdk 7 Home%
$ mvn -Pall clean
$ mvn -Pall -DskipTests=false clean compile package install
$ mvn eclipse:eclipse

[H3] Deployment Process

[H4] Installation Host Information

1. Ranger Admin Tool Component (ranger-%version-number%-admin.tar.gz) should be installed on a host where Policy Admin Tool web application runs on port 6080 (default).

2. Ranger User Synchronization Component (ranger-%version-number%-usersync.tar.gz) should be installed on a host to synchronize the external user/group information into Ranger database via Ranger Admin Tool.

3. Ranger Component plugin should be installed on the component boxes:

(a) HDFS Plugin needs to be installed on Name Node hosts

(b) Hive Plugin needs to be installed on HiveServer2 hosts

(c) HBase Plugin needs to be installed on both Master and Regional Server nodes.

(d) Knox Plugin needs to be installed on Knox hosts.

(e) Storm Plugin needs to be installed on Storm hosts.

[H4] Installation Process

1. Download the tar.gz file into a temporary folder in the box where it needs to be installed.

2. Expand the tar.gz file into /usr/lib/ranger/ folder

3. Go to the component name under the expanded folder (e.g. /usr/lib/ranger/ranger-%version-number%-admin/)

4. Modify the install.properties file with appropriate variables

5. If the module has setup.sh,
Execute ./setup.sh
If the setup.sh file does not exists,
Execute ./enable-%component%-plugin.sh
