Richard commented on SQOOP-1776:
--------------------------------

Hadoop 2.5.1 or before: all classes used to implement Kerberos support is in 
Hadoop-auth component.
Hadoop 2.6.0: There is a refactor to support delegation token in Hadoop [4]. 
Most components in Hadoop, such as RM, Httpfs and Kms, have rewritten 
authentication mechanism to use delegation token. 
{{https://issues.apache.org/jira/browse/HADOOP-10771}}

So, this task is to refactor authentication mechanism to support delegation 
token.
