Ashvin commented on HDFS-14390:
-------------------------------
I uploaded a new patch [^HDFS-14390.002.patch]. As mentioned earlier, the
{{clientPrincipal}} is removed. It also addresses the {{javac}} warning. The
tests uses on {{MiniKdc}}. Based on javadoc and other tests using it, it seems
the recommended way to initialize it is in a {{static BeforeClass}} method.
Hence the new patch does not change the test setup.

> With {{PROVIDED}} storage (-HDFS-9806)-, HDFS can address data stored in
> external storage systems. This feature is not supported in a secure HDFS
> cluster. The {{AliasMap}} service does not support kerberos, and as a result
> the cluster nodes will fail to communicate with it. This JIRA is to enable
> kerberos support for the {{AliasMap}} service.
