public final class ApplicationTable
extends BaseTable<ApplicationTable>

The application table as column families info, config and metrics. Info stores information about a YARN application entity, config stores configuration data of a YARN application, metrics stores the metrics of a YARN application. This table is entirely analogous to the entity table but created for better performance. Example application table record:
