-This exercise creates two tables in HBase, students and clicks, that you can query with Drill. As an HBase user, you most likely are running Drill in distributed mode, in which Drill might start as a service. If you are not an HBase user and just kicking the tires, you might use the Drill Sandbox on a single-node cluster (embedded mode). In this case, you need to [start Drill]({{ site.baseurl }}/docs/install-drill/) before performing step 5 of this exercise. On the Drill Sandbox, HBase tables you create will be located in: `/mapr/demo.mapr.com/tables`
