Hadoop/cygwin failure in bin/hadoop tasktracker command

Question

i am following http://ebiquity.umbc.edu/Tutorials/Hadoop/00%20-%20Intro.html

Start the namenode in the first window by executing cd hadoop-0.19.1 bin/hadoop namenode Start the secondary namenode in the second window by executing cd hadoop-0.19.1 bin/hadoop secondarynamenode Start the job tracker the third window by executing cd hadoop-0.19.1 bin/hadoop jobtracker Start the data node the fourth window by executing cd hadoop-0.19.1 bin/hadoop datanode Start the task tracker the fifth window by executing cd hadoop-0.19.1 bin/hadoop tasktracker

till "bin/hadoop datanode" is working fine the last one for "bin/hadoop tasktracker"

this is what i gets
