[Beowulf] Hadoop's Uncomfortable Fit in HPC

Important paragraph:

"Some larger players in the HPC arena have begun to provide rich support
for high-performance parallel file systems as a complete alternative to
HDFS.  IBM's GPFS file system has a file placement optimization (FPO)
capability that allows GPFS to act as a drop-in replacement for HDFS, and
Intel was selling native Lustre support before they sold IDH to Cloudera."

And Intel still are but are bundling their Lustre <-> Hadoop connector with
their commercially supported Lustre product "IEEL". It's not OSS however.
They support Cloudera (obviously as they just sunk $740m) and Apache
Hadoop. There is also support for SLURM as a scheduler however I don't have
a nice link. These bits should mean that Hadoop can play nicely as a
"normal" HPC application.
