dev 
 I submit a spark application in mode yarn cluster to a cluster with kerberos. 
In this application, it will successfully query a hive table, but when it try 
to query a carbon table, it failed with infomation "Delegation Token can be 
issued only with kerberos or web authentication".  

If I submit this application in mode yarn client, both hive table and carbon 
table will both success. 

And If I submit this application in mode yarn cluster on another cluster 
without kerberos, both hive table and carbon table will both success.
