A successful Hadoop cluster design comes from its availability when one or many of its nodes fails for any reason. It becomes essential to ensure a high available Hadoop cluster before moving to production. By virtue of its simplicity, Sahara facilitates an HA Hadoop setup with minimum manual configuration. The chapter has introduced how to launch a high available Hadoop cluster based on few requirements settings. Although the current version supports HA on HDFS only for the HDP and CDH plugins, the Sahara project keeps growing and covering more advanced features for other plugins. By the end of this chapter, most of the advanced functionalities provided by Sahara have been covered. On the other hand, within every OpenStack release, more bugs are being fixed and many new features are being improved.
