Steve Loughran commented on HADOOP-13945:
-----------------------------------------
in {{RemoteWasbAuthorizerImpl.getSASKey()}} ,InterruptedException should be
rethrow, or the thread interrupte state set...don't want to lose the shutdown
event.
as any raised IOE text isn't preserved, the {{SASKeyGenerationException}} which
be raised afterwards will lose the text/stack trace. Needs to be preserved for
the sake of the support team.
Similarly, {{RemoteWasbAuthorizerImpl.init()}} logs an IOE but doesn't retain
it to rethrow. Should be used to init the cause in the wasb exception.

> Current implementation of Azure storage client for Hadoop ({{WASB}}) does not
> support Kerberos Authentication and FileSystem authorization, which makes it
> unusable in secure environments with multi user setup.
> To make {{WASB}} client more suitable to run in Secure environments, there
> are 2 initiatives under way for providing the authorization (HADOOP-13930)
> and fine grained access control (HADOOP-13863) support.
> This JIRA is created to add Kerberos and delegation token support to {{WASB}}
> client to fetch Azure Storage SAS keys (from Remote service as discussed in
> HADOOP-13863), which provides fine grained timed access to containers and
> blobs.
> For delegation token management, the proposal is it use the same REST service
> which being used to generate the SAS Keys.
