Figure 11-2. Properties for Hunk provider cdh5
Note that the Hadoop version in Figure 11-2 is set to YARN to reflect the CDH5 YARN version. It has not been
necessary to specify the Hadoop supplier name.
Now, click Cancel to leave the cdh5 properties view, and click on the Virtual Indexes tab. For the chapter
example, this tab shows that a single virtual index has been created in Hunk called cdh5_vindex, as shown in
Figure 11-3 .
Figure 11-3. Hunk virtual index cdh5_vindex
Virtual indexes are the means by which hunk accesses the Hadoop cluster-based data. They enable Hunk to use
Map Reduce against the data and present the results within Hunk reports. By selecting the cdh5_vindex entry, you can
examine the attributes of this virtual index (Figure 11-4 ). Currently, the entry, which was defined in the props.conf file,
doesn't have much detail.It just defines the directory on HDFS where the CSV data is located. Click the Cancel button
to exit this property details screen.
