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.
