Thanks [~liuml07] for reviewing the patch. Attached another patch containing the checkstyle fixes excluding the fix for the {{FileLength}} related warning.

> Azure: RemoteWasbAuthorizerImpl and RemoteSASKeyGeneratorImpl use Kerberos interactive user cache

> Key: HADOOP-14351
> URL: https://issues.apache.org/jira/browse/HADOOP-14351
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure
> Affects Versions: 2.9.0
> Reporter: Santhosh G Nayak
> Assignee: Santhosh G Nayak
> Attachments: HADOOP-14351.1.patch, HADOOP-14351.2.patch
>
>
> Currently, {{RemoteWasbAuthorizerImpl.getRelativeBlobSASUri()}}, {{RemoteWasbAuthorizerImpl.getContainerSASUri()}} and {{RemoteSASKeyGeneratorImpl.authorize()}} use Kerberos interactive user's ticket cache if the kerberos credential is not available for {{UserGroupInformation.getCurrentUser()}} or {{UserGroupInformation.getRealUser()}}.
> It results in usage of interactive user's ticket for impersonation, whenever services try to do File System operations as another user, which is incorrect.
