hdp-cloud

Installs and configures a cluster for use with Ambari

• default.rb - run on all clients
• master.rb - run on the specified master node

Override attributes to your clusters configured settins

To create a user on the cluster, create a new data bag and add JSON like:

{
  "id": "redstack-admin",
  "uid": "1501",
  "keytab_principal": "redstack-admin",
  "keytab_filename": "redstack-admin.headless.keytab",
  "keytab_location": "/user_items/keytabs",
  "keytab_owner": "redstack-admin",
  "keytab_groupowner": "redstack-admin",
  "keytab_permissions": "400",
  "create_hdfs_home": "true",
  "create_ssh_key": "true",
  "regular_user": "true",
  "sudo_user": "true",
  "install_smoke_test": "true",
  "password": "[generated_password_hash]"
}

• Where the value for password is an encrypted password generated by openssl
• The password is encrypted with a general unix crypt hash, it can be created with openssl passwd -1 password_string
• To create a service user, set the regular_user flag to false. This is how to create a service account for something like Hue
• Note that service account are not present in the LDAP server, only as a local account
