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
