The yaml config file

[sunitswn91]

The HdfsFileTopology to be run on local cluster needs a YAML config file. What is this YAML config file? Also I tried running, for trial perposes ( just to see if i'm mentioning the arguments correctly?) the topology as HdfsFileTopology test-topology something.yaml <, and it just ends and gives out the correct format to use the topology>

Usage: HdfsFileTopology [topology name] yaml config file
