@kurtzeborn @HarshaNalluru @jeremymeng Will you help create the branch for adlsgen2 from feature/storage? Or I can create the branch by myself, just check any naming patterns needed for the new branch. I'll change PR destination to the new branch.

[HarshaNalluru]

I suggest feature/storage-adlsgen2. Fine ?
