You reference the MapR distribution for their training material, and its interesting that their version of HDFS is a reimplentation in C++ (MapR-FS). Its part of the reason I settled on MapR to use tools like Apache Drill, because the filesystem becomes usable to non-Hadoop tools via NFS (i.e. Awk).

Given a shift in some categories away from map-reduce to other approaches, could Hadoop eventually just become a collection of distributed filesystems and job schedulers?
