Summary

In this chapter, we looked at the various challenges for integrating a secured Hadoop cluster with Enterprise systems. One of the main concerns for organizations adopting Big Data is its security. Having the ability to manage Hadoop users' identity and authorizations centrally using existing EIM systems clears the first hurdle in the Big Data adoption journey. In this chapter, we looked at the implementation details for integrating EIM systems with the Hadoop KDC and how seamlessly Enterprise existing security process can be easily extended to Hadoop. Another big concern for organizations is usually around network security. In this chapter, we detailed out the implementation approach to enforce perimeter security around the Hadoop cluster and how to provide end users with seamless access from corporate networks to the secured Hadoop cluster using HttpFS, HUE, and Knox Gateway Server.

In the next chapter, we look at another important security concern for Big Data adoption and that...
