Introduction to Hue
Hue is a web-based interactive query editor that enables you to interact with data warehouses. For example, the following image shows a graphic representation of Impala SQL query results that you can generate with Hue:
You can use Hue to:
Explore, browse, and import your data through guided navigation in the left panel of the page:
This panel enables you to:
- Browse your databases
- Drill down to specific tables
- View HDFS directories and cloud storage
- Discover indexes and HBase or Kudu tables
- Find documents
Objects can be tagged for quick retrieval, project association, or to assign a more "human-readable" name, if desired.
Query your data, create a custom dashboard, or schedule repetitive jobs in the central panel of the page:
The central panel of the page provides a rich toolset, including:
- Versatile editors that enable you to create a wide variety of scripts.
- Dashboards that you can create "on-the-fly" by dragging and dropping elements into the central panel of the Hue interface. No programming is required. Then you can use your custom dashboard to explore your data.
- Schedulers that you can create by dragging and dropping, just like the dashboards feature. This feature enables you to create custom workflows and to schedule them to run automatically on a regular basis. A monitoring interface shows the progress, logs, and makes it possible to stop or pause jobs.
