Just point at your Hadoop cluster to analyze your data
Unlike other Hadoop analysis software, getting Hadoop data to work with Tableau is easy: Just point at your cluster! You do need Hive installed on your Hadoop cluster, which is a common component that provides a SQL interface to Hadoop.
There’s no special configuration you need for either Tableau or Hadoop. Cloudera, Hortonworks, and MapR Hadoop distributions are simply another data source in Tableau. You can connect with no programming, then use Tableau's drag-and-drop interface to visualize your data.
Here we have weather data from a set of XML objects, now stored in a Hadoop cluster. Tableau’s powerful visualization capabilities let you create maps, charts, and dashboards easily.
