Looks, that is permissions related issue on local dirs
There is an issue filed in mapred, related to this problem
https://issues.apache.org/jira/browse/MAPREDUCE-2921
Can you please provide permissions explicitely and try?
Regards,

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
