Atul Sikaria commented on HADOOP-14824:
---------------------------------------
The change is in MSI (one of the auth mechanisms), not in ADLS - this patch
just ensures that users of MSI don't break.
Also, this impacts only people who use MSI as the auth mechanism. Given MSI is
very recent (GA is later this month), we don't expect there to be many users.
> Update ADLS SDK to 2.2.2 for MSI fix

> Recently there was a change to MSI-based authentication in Azure VMs: the
> auth request to localhost now requires a new header (Metadata) with a fixed
> value (true). Existing clients that do not send this header will fail to get
> token.
> To address this, the datalake SDK was updated in version 2.2.2 to send this
> header in the token request.
> This patch is to use the updated sdk in Hadoop.
