This quickstart gets you going with Azure Databricks: you create a cluster and a notebook, create a table from a dataset, query the table, and display the query results.
- An Azure portal account
- An existing Azure Databricks workspace
See Azure Portal Quickstart for instructions.
Log in to the Azure portal.
In the Azure portal, go to the Azure Databricks workspace and click Launch Workspace. You’ll see the Azure Databricks landing page.
From the sidebar at the left and the New list, you access fundamental Databricks entities: the Workspace, clusters, tables, notebooks, jobs, and libraries. The Workspace is the special root folder that stores your Databricks assets, such as notebooks and libraries, and the data that you import.
To get help, click the question icon at the top right-hand corner.
A cluster is a collection of Databricks computation resources. To create a cluster:
In the sidebar, click the Clusters button .
On the Clusters page, click Create Cluster.
On the New Cluster page, specify a cluster name and select 4.0 (includes Apache Spark 2.3.0, Scala 11) in the Databricks Runtime Version drop-down.
Click Create Cluster.
A notebook is a collection of cells that run computations on a Spark cluster. To create a notebook in the Workspace:
In the sidebar, click the Workspace button .
In the Workspace folder, select Create > Notebook.
On the Create Notebook dialog, enter a name and select Python in the Language drop-down.
Click Create. The notebook opens with an empty cell at the top.
Run a SQL statement to create a temporary table using data from a sample CSV data file available in Azure Databricks Datasets.
Copy and paste this code snippet into the notebook cell. The
pathvalue denotes the location of the sample CSV file.
%sql DROP TABLE IF EXISTS diamonds; CREATE TEMPORARY TABLE diamonds USING csv OPTIONS (path "/databricks-datasets/Rdatasets/data-001/csv/ggplot2/diamonds.csv", header "true")
Press SHIFT + ENTER. The notebook automatically attaches to the cluster you created in Step 2, creates the table, loads the data, and returns
Run a SQL statement to query the table for the average diamond price by color.
To add a cell to the notebook, mouse over the cell bottom and click the icon.
Copy this snippet and paste it in the cell.
%sql select color, avg(price) as price from diamonds group by color
Press SHIFT + ENTER. The notebook displays a table of diamond color and average price.
Display a chart of the average diamond price by color.
Click the Bar chart icon .
Click Plot Options.
Drag color into the Keys box.
Drag price into the Values box.
In the Aggregation drop-down, select AVG.
Click Apply to display the bar chart.
We’ve now covered the basics of Databricks, including creating a cluster and a notebook, running SQL commands in the notebook, and displaying results.
