Yan Li reports that Azure Data Lake Analytics no longer requires waiting for approval:
We’re happy to announce that we’ve made it much faster to get started with the Data Lake Store and Analytics services starting today. Before today, when you tried to sign up for these services you had to go through an approval process that introduced a delay of at least one hour.
Now, you no longer have to wait for approval, and you can simply create an account immediately.
Yan also has some “getting started” links to help you out, now that you don’t have to wait for an account.
