It provides me with ease of use when dealing with both HBase, Hive/Spark SQL queries as well as other Java applications that interface directly or indirectly (i.e., through Kafka) with it. The documentation is also very good in terms of explaining how everything works together for you so there's no need to go digging around forums. I do wish they had an easier way to get started by providing more examples out-of-the box but overall this has been great! We've used hyperTable internally within our organization while working with Apache Spark Streaming projects which are all written via java APIs. This allows us quick integration into existing codebases without having to rewrite them from scratch.
