Advantage is that schemas don’t need to be created in order to search for patterns, since Hadoop is leveraged. Makes sense, since by creating a schema the user is already making assumptions about where the patterns exist. By doing a schema-less analysis, it’s possible to find unexpected anomalies within patterns and to find entirely new patterns.
