title: hadoop with cygwin: hadoop-daemon.sh: not found
body: <p>I am installing hadoop on cygwin. I have a windows 7 64-bit machine and i've been following the instrux here: <a href="http://alans.se/blog/2010/hadoop-hbase-cygwin-windows-7-x64/#software" rel="nofollow">http://alans.se/blog/2010/hadoop-hbase-cygwin-windows-7-x64/#software</a>. I have passwordless SSH setup in cygwin and have installed hadoop 0.20.2. </p>
  
  <p>When I issue bin/start-dfs.sh, I get the following:</p>
  
  <pre><code>starting namenode, logging to /usr/local/hadoop-0.20.2/bin/../logs/hadoop-T3S-namenode-t3s780mon.out
  localhost: /usr/local/hadoop-0.20.2/bin/hadoop-daemon.sh: /usr/local/hadoop-0.20.2/bin/hadoop-daemon.sh: not found
  localhost: /usr/local/hadoop-0.20.2/bin/hadoop-daemon.sh: /usr/local/hadoop-0.20.2/bin/hadoop-daemon.sh: not found
  </code></pre>
  
  <p>The file exists in that exact location. The permissions seem fine (it's owned by "Administrators" and i'm running as a user who has "Administrators" privilege. And anyway, it's finding and executing other scripts before getting to this point. This output happens at this line in the bin/slaves.sh script</p>
  
  <pre><code>for slave in `cat "$HOSTLIST"|sed  "s/#.*$//;/^$/d"`; do
   ssh $HADOOP_SSH_OPTS $slave $"${@// /\\ }" \
     2&gt;&amp;1 | sed "s/^/$slave: /" &amp;
   if [ "$HADOOP_SLAVE_SLEEP" != "" ]; then
     echo "@@@ slave.sh is SLEEPING"
     sleep $HADOOP_SLAVE_SLEEP
   fi
  done
  </code></pre>
  
  <p>Specifically at the "ssh..." line. And essentially, what that's calling is (when it all the script variables are resolved):</p>
  
  <pre><code>ssh localhost cd /usr/local/hadoop-0.20.2/bin/.. ; /usr/local/hadoop-0.20.2/bin/hadoop-daemon.sh --config /usr/local/hadoop-0.20.2/bin/../conf start datanode
  </code></pre>
  
  <p>which, when i run manually (i.e., pasting it into the cygwin console) does not return any such error.</p>
  
  <p>So what's causing this script to fail at this point with this particular message? I assume it's related to how i have ssh set up, but can't puzzle it out, since i feel i've done all in a standard way...</p>
  
  <p>thanks for any help / ideas / clues.</p>
