Custom parcels and CSDs allow partners and clients to bring their libraries and packages to CDP.  Traditionally, customers would use recipes to install parcels and CSDs or manually copy them to appropriate nodes. But, with CDP Public Cloud, you need a modular approach to do this. To address that need, Cloudera has developed the capability of specifying the parcel and CSD information as part of the cluster template (blueprint). With this approach, the parcel and CSD will get downloaded, distributed and activated as part of the cluster build process. In the example below, FLINK 1.12 should be installed by default, but a different version of the FLINK parcel and CSD are passed for the Cloudera Manager to download, distribute and activate. FLINK service is added to the cluster during the cluster import. High level steps are as follows: Modify Cluster Template to define roletype, servicetype, hostgroup configs.  Get the Image Catalog ID Create a Custom Request Template : add Parcels/CSDs ( cli parameter)  Create/Update Manifest json   CLI : Provision DH cluster using CLI Modify Cluster Template CDP UI > Management Console > Shared Resources > Create Cluster Template. e.g:        { "cdhVersion": "7.2.12", "displayName": "dataengineering", "blueprintUpgradeOption": "MAINTENANCE_UPGRADE_GA", "services": [ { "refName": "$partner_solution", "serviceType": "$custom_solution_name", "serviceConfigs": [ { "name": "partner_solution_license_specification", "value": "XXXXXXXXX" }, { "name": "$partner_solution_dashboard_realm", "value": "cloudera-cdp-test-1" } ], "roleConfigGroups": [ { "refName": "$partner_solution-AGENT-BASE", "roleType": "$partner_solution_AGENT", "base": true }, { "refName": "$partner_solution-SUPERVISOR-BASE", "roleType": "$partner_solution_SUPERVISOR", "base": true }, { "refName": "$partner_solution-COLLECTOR-BASE", "roleType": "$partner_solution_COLLECTOR", "base": true } ] }, { "refName": "worker", --- Modify compute, master, worker, gatewat hostgroups as needed -- "cardinality": 3, "roleConfigGroupsRefNames": [ "hdfs-DATANODE-BASE", "yarn-NODEMANAGER-WORKER", "$partner_solution_AGENT-BASE", "$partner_solution_COLLECTOR-BASE" ] },       Note the cluster template name.(e.g: 7.2.12 Data Engineering: Customer template) Get the Image Catalog ID Get the AMI-ID of the DataLake. Log on the CDP > DataLake > Image Details (for a new/recently created environments). Create a temporary Datahub to get the AMI-ID, if the DL was created a while ago. Open the Image Catalog json Search for AMI-ID in the Image Catalog json Note the UUID. Make sure the image is in the right region and the cloud provider (AWS/Azure). Create a Custom Request Template Add environment name: This is where the cluster will be deployed.  BlueprintName - from the first step(7.2.12 Data Engineering: Customer template)       "name": “DEFINITION_NAME”, "environmentName": “CDP_ENV_NAME”, "cluster": { "databases": [], "blueprintName": “7.2.12 Data Engineering: Customer template"         Add CM base url, products: name, version and Parcels.

Note to use file:// cluster-name: Name of the cluster    NOTE: Manifest File And Naming Of The Parcel Parcel filenames must follow a specific format: [name]-[version]-[distro suffix].parcel. The list of valid distro suffixes is available here. Otherwise, improper naming will lead to parcel not being recognized during the cluster installation. It is also necessary to have a manifest file in the parcel directory. The manifest creator will create a manifest.json file for a directory of parcels, so that directory can be served as a parcel repository.
