With the above changes i.e change all the files to file:///xyz with unix style directory separator, HDP for windows works like a charm on Windows 7 too.
Some more observations were
if you have multiple network cards, then namenode is picking up some ip, than datanode. So use browser URL for namenode as one of the IP’s you have.
Combine this install with http://bigdata.red-gate.com/ explorer install, would make you forget about HDFS commands.
Working on HDF windows is awesome.
