Try adding a dependency on python-hdfs to datamake.  This might break everything.
python-hdfs isn't distributed, so fetch it from source from github
Use webhdfs-py instead of python-hdfs
Try requiring directly from github as we fail to find a downloadable packaged version of webhdfs-py
Give up trying to use a packaged version of webhdfs-py and just copy the bits we need.
Case screw-up on HDFS/Hdfs
Some debug output
Cast port to int to avoid exception from socket layer
HdfsArtifact requires a uri() method
Start of adding namespace support, which is a pre-requisite for datamake accepting multiple files that might have inter-flow dependencies
Read multiple datamake JSON configs; amalgamate into single template resolver; allow references between namespaces
Remove some debug printing, and tidy up the --showgraph output
Merge branch 'ph_namespace_support' of github.com:songkick/datamake into ph_namespace_support
Fix broken tests that were not namespace-aware
Ignore .pyc files
Some legacy support for pre-namespace config files so that the 'main' task can still be specified on the cmdline without namespacing
Remove commented-out code and stuff it used
Merge pull request #4 from songkick/master

Add support for HDFS artifacts, task namespacing and cross-config file dependencies
