Counterpoint: Why Some Hadoop Adapters Make *Perfect* Sense
Jeff Darcy’s reply to Daniel Abadi’s “Why Database-To-Hadoop Connectors Are Fundamentally Flawed and Entirely Unnecessary“:
Going back to Daniel’s argument, RDBMS-to-Hadoop connectors are indeed silly because they incur a migration cost without adding semantic value. Moving from one structured silo to another structured silo really is a waste of time. That is also exactly why filesystem-to-Hadoop connectors do make sense, because they flip that equation on its head — they do add semantic value, and they avoid a migration cost that would otherwise exist when importing data into HDFS. Things like GlusterFS’s UFO or MapR’s “direct access NFS” decrease total time to solution vs. the HDFS baseline.
