Stacki is a Linux server provisioning tool designed for rapid deployment to bare metal or virtual machines with no prerequisites. It facilitates the installation of the Hortonworks Data Platform (HDP) through a simple process of adding and configuring software pallets and managing cluster nodes. Additionally, it supports various functionalities, including partitioning, disk formatting, and Ambari appliance creation for efficient Hadoop deployment.

2. Open Source Stack Installer
Stacki is a very fast and ultra reliable Linux server provisioning tool … at scale.
With zero prerequisites for taking systems from bare metal to a ping and prompt.

3. Stuff it does
 Installs to bare metal or VMs that look like bare metal
 Kickstart based
 Parallel formatting of disk
 Parallel Sharing of RPMs
 CentOS/RHEL
 Networking
 Multiple subnets, vlaning, bonding.
 Storage
 Controller config
 Partitioning
Whatever you can do in Linux, you can do with Stacki only clustered

4. Stacki and Hortonworks Data Platform

5. Hortonworks – stacki-hdp-bridge pallet
 Add/enable/run
 Stacki creates ambari appliance
 Download software as pallets (isos)
 Add/enable HDP and Ambari
 Run gethdp script
 Or download (links in documentation)
 Assign a node to be Ambari deployment.
 Do partitions and preps backend nodes for Hadoop.
 Install all.
 Go to Ambari interface to deploy Hadoop.
 Current versions: (updated /export/HDP/hdp.cfg for new versions)
 distribution = 2.x
 os = centos7
 ambari = 2.4.2.0
 hdp = 2.5.3.0

6. Augment the “default” Box
1) Replace the “os” pallet with the “CentOS” and “CentOS-
Updates” pallets
2) Add the Hortonworks pallets: “HDP”, “HDP-UTILS”,
“Updates-ambari” or run /export/HDP/gethdp.py
3) Add a pallet to glue the two layers together: “stacki-
hdp-bridge”

7. Specify One Host as the “Ambari” appliance
“backend-0-0” will be automatically configured with Ambari
Install the node and then point your web browser at it

8. Reinstall All Backend Nodes
Wipe all hardware disk array configuration and rebuild all the LUNs:
◦ stack set host attr ambari backend attr=nukecontroller value=true
Remove all partitions then repartition and reformat the disks:
◦ stack set host attr ambari backend attr=nukedisks value=true
Instruct nodes to install on next PXE boot:
◦ stack set host boot ambari backend action=install
