IV CONCLUSIONS
In this paper, we introduced collaborative big data analytics platform. The big data platform provides two kinds of web portals: web service portal for collaboration and analytics portal for developing BDaaS services. We have enhanced access control and YARN for multi-tenancy so that the platform can support collaboration among actors.
Web service portal is a common web interface for communication. Analytics portal is linked to web service portal and supports various big data management and development tools. Finally, we demonstrated CCTV metadata analytics as an analytics service.
