We have been improving the developer experience for Azure Data Lake developers. Here is what we added in December.
U-SQL local run enhancements
The DataRoot for a U-SQL local run can now be configured. To set it, click Menu
> Data Lake
> Options and Settings
.The experience for local development in Server Explorer is same as with the cluster development experience. Create
metadata operations now work for databases, assemblies, schemas, and tables.
Sample applications are updated, so you can run the scripts locally without copying the sample data.
Error message screen update
As shown in the following image, you can see your job errors more clearly:
Expand * columns
We’ve added editor support for expanding the columns for *. By hovering your cursor, you’ll see a hint (similar to what C# does with adding namespaces). You can also use the same shortcut as C# (Alt-Shift-F10) to expand columns.
