Description

If Map-Reduce jobs are started with by a proxy user that has already the delegation tokens, we get an exception on "obtain token" since the proxy user doesn't have the kerberos auth.

For example:

• If we use oozie to execute RowCounter - oozie will get the tokens required (HBASE_AUTH_TOKEN) and it will start the RowCounter. Once the RowCounter tries to obtain the token, it will get an exception.
• If we use oozie to execute LoadIncrementalHFiles - oozie will get the tokens required (HDFS_DELEGATION_TOKEN) and it will start the LoadIncrementalHFiles. Once the LoadIncrementalHFiles tries to obtain the token, it will get an exception.
