In this section, we will learn how to create a Data Lake Analytics job that will debug and run a U-SQL script. This job will summarize data from the file created by Task 1 in the preceding data factory pipeline (the task that imports SQL Server data into a blob file). The summary data will be copied to a new file on the blob storage.
With U-SQL, we can join different blob files and manipulate/summarize the data. We can also import data from different data sources. However, in this section, we will only provide a very basic U-SQL as an example.
Let's get started...

Click on Add data source:
Fill in the details:
You should see the added blob storage in the list:
You can explore the containers...
