    <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>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
