Can you also add description of the type of credentials that would be missing without this change ?

Doing 'submit patch' to kick off the tests.

> The credentials present in the current UGI i.e. UserGroupInformation.getCurrentUser().getCredentials() isn't passed to the Tez session. It is instantiated with null credentials 
> session = TezClient.create("HIVE-" + sessionId, tezConfig, true,
>         commonLocalResources, null);
> In this case, Tez fails to access resources even if the tokens are available in memory.
