Subject credential in UserGroupInformation
Date Fri, 23 May 2014 15:59:07 GMT

I have view the code about UGI in spark. If spark interactive with kerberos HDFS, The spark
will apply delegate token in scheduler side, and stored as credential into the UGI; And the
credential will be transferred to spark executor so that they can authenticate the HDFS. My
question is how does UGI do these credential transfer? does the credential transferred in
encrypted way?

Thanks in advance.
