Abstract: A system and a method for secure operator onboarding and creating an ingest job agent for secure multitenant operations of a distributed computing cluster are provided. Embodiments automate multitenant operations for distributed computing clusters. These operations include automation of operator onboarding, creation of logically segregated distributed data stores within the distributed computing clusters for the on-boarded operator, and creation of ingest agents with security isolation for transfer of large quantities of files into the distributed computing clusters. Embodiments provide multitenant security, in which the same Hadoop cluster serves multiple operators with each operator's data and processes in effective isolation. In this manner, multitenant security keeps each user's data storage and operations on the Hadoop cluster separated from other operators.

Abstract: A ventilated handlebar, such as a bicycle handlebar is disclosed. The ventilated handlebar comprises an air-intake aperture that is oriented in the direction of forward travel of the vehicle and an air distribution channel that is connected to the air-intake apertures and is also connected to a series of air-discharge openings to ventilate the hand grip area of the handlebar, thereby promoting a cooling effect on the rider's palms resulting in cooling effect on the rider's body thereby reducing the rider's fatigue.
