Hi

this is the log file error message:

ERROR org.apache.hadoop.mapred.TaskTracker: Can not start task tracker 
because
java.io.IOException: Failed to set permissions of path: 
\home\Administrator\software\hadoop-tmp\mapred\local\ttprivate to 0700

thanks for the hint,
you mean there is no way to use cygwin 1.7 by hadoop?
how java can know the cygwin/home/...?

Cygwin has different paths- Java needs to see /cygwin/home/....

Try the GnuWin32 package instead (it is on sourceforge). It is also ports of
gnu utilities, but they live directly in DOS-land instead of making a weird
wrapper that breaks everything.
