I have just updated to cygwin 1.7 and if I try to format the namenode, i get
the following warning by cygwin.
$ bin/hadoop namenode -format
cygwin warning:
MS-DOS style path detected: C:\cygwin\home\bike\HADOOP~1.2\/build/native
Preferred POSIX equivalent is: /home/bike/HADOOP~1.2/build/native
CYGWIN environment variable option "nodosfilewarning" turns off this
warning.
Consult the user's guide for more details about POSIX paths:

Re-format filesystem in \tmp\hadoop-bike\dfs\name ? (Y or N)
---------------------------
Just wondering, is it possible that the error is because namenode format it
according to windows namespace so hadoop cannot find /work/temp folder?
would like to hear some feedback from the community
thanks
