Sure, ^^
when I run {namenode -fromat} it makes dfs in c:/tmp/
administrator_hadoop/....
after that by running "start-all.sh" every thing is OK, all daemons run
except tasktracker.
My current user in administrator, but tacktracker runs by cyg_server
user that made by cygwin in installation time;This is a part of log file:
