Body
Considering the error message (<code>[...]6_0/work/tmp does not exist</code>), the first issues to check are: <ul> <li>the right access under <code>c:\tmp</code></li> <li>the initialization steps for <a href="http://www.alphaworks.ibm.com/tech/mapreducetools" rel="nofollow noreferrer">this plugin</a> to run correctly: see <a href="http://www.ibm.com/developerworks/forums/thread.jspa?messageID=14202359&tstart=0#14202359" rel="nofollow noreferrer">this thread</a></li> </ul> Extract: <blockquote> If you installed it correctly, you should be able to start the MapReduce perspective and Map/Reduce view. Both are under <code>Window > Open Perspective</code> and <code>Show View</code> respectively. <ul> <li>Click the blue elephant on the upper right corner of the <code>Map/Reduce</code> view. It'll bring up a configuration window.</li> <li>Type in any name for the the Location Name. I just called it localhost cluster.</li> <li>Set the port numbers for Map/Reduce Master and DFS Master. Look in your conf/hadoop-<code>site.xml</code> for "<code>mapred.job.tracker</code>" and "<code>dfs.default.name</code>" respectively. If not in that file, then it is probably in <code>hadoop-default.xml</code> or <code>hadoop-env.xml</code>.</li> <li>Click "<code>Advanced Parameters</code>" tab and set the "<code>mapred.job.tracker</code>" parameter. For some reason it doesn't automatically change when you change it in the "General" tab.</li> <li>User name should be whoever owns hadoop. For me, it is just my login, others make a separate "hadoop" user for hadoop.</li> <li>If you have done everything correctly, you should be able to click the triangles on the left to span the hierarchy view.</li> </ul> </blockquote>

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.
