-## TDP repositories
+## Local build environment for components
 
-The TDP project is composed of multiple repositories:
-- [tdp-collection](https://github.com/TOSIT-IO/tdp-collection): main Ansible collection to deploy TDP core components.
-- [tdp-collection-extras](https://github.com/TOSIT-IO/tdp-collection-extras): Ansible collection to deploy extra components that are not part of TDP core.
-- [tdp-collection-prerequisites](https://github.com/TOSIT-IO/tdp-collection-prerequisites): Ansible collection to deploy prerequisite components to a TDP installation (i.e.: KDC, PostgreSQL, etc.).
-- [tdp-lib](https://github.com/TOSIT-IO/tdp-lib): Python library to configure, manage and deploy TDP.
-- [tdp-server](https://github.com/TOSIT-IO/tdp-server): REST API for tdp-lib orchestration.
-- [tdp-ui](https://github.com/TOSIT-IO/tdp-ui): Web UI for TDP clusters deployment and configuration, uses tdp-server.
-- [tdp-getting-started](https://github.com/TOSIT-IO/tdp-getting-started): A ready to deploy TDP virtual environment based of Vagrant showcasing how to use every component of TDP.
+In order to build the TDP components, two distinct images have been made:
 
-Each component of TDP also has its own repository.
+- [tdp-builder]((build-env/README.md)) containing Maven for Java compilation of the Apache Hadoop environment components.
+- [tdp-builder-python](build-env-python/README.md) containing a manylinux2014 image with different Python versions for the packaging of JupyterHub, Jupyterlab, Sparkmagic and Hue.

+The components' versions and their repositories are found in [tdp-core](https://www.trunkdataplatform.io/en/discover/stacks/tdp2-0) and must be compiled in the follwing order:
 
-Versions are approximately based on the [HDP 3.1.5 release](https://docs.cloudera.com/HDPDocuments/HDP3/HDP-3.1.5/release-notes/content/hdp_relnotes.html).
+- Zookeeper
+- Hadoop
+- Tez
+- Spark3
+- Hive
+- HBase
+- Ranger
+- Phoenix
+- Phoenix-queryserver
+- Knox
+- HBase Operator tools
+- Iceberg
 
-**Note**: For some projects, the Apache foundation maintains sometimes a branch with this the components on which are backported fixes and features. We will be using these branches as much as possible if they are maintained and compatible.
+The Maven compilation commands of the different components can be found in the `tdp/README.md` file of each project.
 
-### TDP Extras
+### tdp-builder-python
 
-"TDP Extras" carries some projects that cannot be integrated to "TDP Core". There can be different reasons that keep the project outside of the core:
+Although the python coded components use the same [tdp-builder-python](build-env-python/README.md) image, they must be packaged seperately in different containers since each component needs its own envrionment:
 
-- The project is not judged as a key component of the Hadoop ecosystem. This is the case of Airflow.
-- The project is not active enough. This is the case of Livy that has not been updated in 2 years.
-- The project has some incompatibilities with other "TDP Core" projects' releases. This is the case of Kafka 2.X that relies on ZooKeeper 3.5.X (and cannot use the ZooKeeper 3.4.6 of "TDP Core").

+### Special case for the Apache Livy compilation
 
-**Note:** A project can graduate from "TDP Extras" to "TDP Core" if enough people are supporting it and/or if it is made compatible with all the other projects of the stack.
+Apache Incubator Livy has its own compilation environment with its own instrsuctions which can be found in the [Incubator Livy project](https://github.com/TOSIT-IO/incubator-livy/tree/branch-0.9.0-fix/tdp).

-## TDP Components release
-
-Every TDP initial release is built from a reference branch on the Apache Git repository according to the above tables. The main change from the original branches is the version declaration in the pom.xml files.
-
-## Building / Testing environment
-
-The builds / unit testing of the Maven Java projects of each component above can be run in Kubernetes pods which are scheduled by a Jenkins installation also running on Kubernetes.
-Kubernetes pods scheduling allows for **truly** reproducible and isolated builds. Jenkins' strong integration with the Java ecosystem is a perfect match to build the components of the distribution.

-### Kubernetes
-
-Kubernetes was installed on Ubuntu 20.04 Virtual Machines with [kubeadm](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/).
-
-**Note:** It is strongly recommended to deploy a Storage Class in order to have persistence on the Kubernetes cluster (useful for Jenkins among others). In our case, we are using [Rook](https://rook.io/) on physical drives attached to the Kubernetes cluster's VMs.
-
-### Jenkins
-
-Jenkins is used to trigger the builds which is the same process for every component of the stack:
-
-- Git clone the sources
-- Build the project
-- Run the unit tests
-- Publish the artifacts to a remote repository
-
-Jenkins was installed on the Kubernetes cluster with the official [jenkinsci Helm chart](https://github.com/jenkinsci/helm-charts).
-
-### Nexus / Docker registry
-
-The building environment needs multiple registries:
-
-- Maven to host the compiled Jars
-- Docker to host the images that we use to build the projects
-- File registry to host the .tar.gz files with the binaries and jars for every compiled projects.
-
-Nexus Repository OSS can assume all three roles, is free and open source.
-
-Nexus OSS was install on the Kubernetes cluster with the [helm chart](https://github.com/Oteemo/charts/tree/master/charts/sonatype-nexus) provided by [Oteemo](https://github.com/Oteemo).
-
-## Local build environment
-
-It is possible to run a local environment for building / small scale testing.
-
-Prerequisite:
-
-- Docker installed and available to your local user
-
-You can start a local building environment with the `bin/start-build-env.sh` script.
-
-**Note:** See `build-env/README.md` for details.
-
-To build TDP component binaries, attach to the running `tdp-builder` container and `git clone` the TDP component repository to it. Each TDP component's `tdp/README.md` has custom instructions to launch the build process.
-Assign a directory path to the `TDP_HOME` variable in the `bin/start-build-env.sh` to control the local path of built TDP binaries.
