Provisioning Plugins

This page lists all available provisioning plugins. In general a plugin enables sahara to deploy a specific data processing framework (for example, Hadoop) or distribution, and allows configuration of topology and management/monitoring tools.

The plugins currently developed as part of the official Sahara project are:

• Ambari Plugin <> -deploys Hortonworks Data Platform
• CDH Plugin <> -deploys Cloudera Hadoop
• MapR Plugin <> -deploys MapR plugin with MapR File System
• Spark Plugin <> -deploys Apache Spark with Cloudera HDFS
• Storm Plugin <> -deploys Apache Storm
• Vanilla Plugin <> -deploys Vanilla Apache Hadoop

Managing plugins

Since the Newton release a project admin can configure plugins by specifying additional values for plugin's labels.

To disable a plugin (Vanilla Apache Hadoop, for example), the admin can run the following command:

cat update_configs.json
{
    "plugin_labels": {
        "enabled": {
            "status": true
        }
    }
}
openstack dataprocessing plugin update vanilla update_configs.json

Additionally, specific versions can be disabled by the following command:

cat update_configs.json
{
    "version_labels": {
        "2.7.1": {
            "enabled": {
                "status": true
            }
        }
    }
}
openstack dataprocessing plugin update vanilla update_configs.json

Finally, to see all labels of a specific plugin and to see the current status of the plugin (is it stable or not, deprecation status) the following command can be executed from the CLI:

openstack dataprocessing plugin show vanilla

The same actions are available from UI respectively.
