class JsonEventLogger[T <: KyuubiEvent] extends AbstractService with EventLogger[T] with Logging

This event logger logs Kyuubi engine events in JSON file format. The hierarchical directory structure is: ${ENGINE_EVENT_JSON_LOG_PATH}/${eventType}/day=${date}/${logName}.json The ${eventType} is based on core concepts of the Kyuubi systems, e.g. engine/session/statement The ${date} is based on the time of events, e.g. engine.startTime, statement.startTime
