-----------------------------------------

             Summary: Azure: Add Kerberos and Delegation token support to WASB client.
                 Key: HADOOP-13945
                 URL: https://issues.apache.org/jira/browse/HADOOP-13945
             Project: Hadoop Common
          Issue Type: Improvement
          Components: azure, fs/azure
    Affects Versions: 2.8.0
            Reporter: Santhosh G Nayak


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.
