    <p>I was using the eclipse plugin for hadoop. I can see all the files in HDFS by making a hadoop server but when I try to run the wordcount.java file from the eclipse, it gives me exception whereas from the terminal it runs smoothly. The exception is below.</p> <pre><code>2/11/14 04:09:06 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 12/11/14 04:09:06 WARN mapred.JobClient: No job jar file set.

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.
