Some people were skeptical of the tuning for HBase, and an HBase developer criticized their methodology, given the especially poor performance shown for HBase. The paper authors themselves indicated that they had considerable trouble setting up the HBase system. Which in a way validates the comments of some here that HBase is fickle and can be difficult to tune, though it still means that the results in this paper for HBase are not valid, when compared to the other systems.
In the interest of disclosure, it should be mentioned here that jbellis is a principle corporate backer of Cassandra.
