Subject Hadoop Security
Date Thu, 18 Feb 2010 05:57:51 GMT
hi all
   i am doing my research in security issues of hadoop.i have noticed that
security can be attained under three heads like user authentication,data
transfer while running hadoop service and HDFS level.
  Analyzed that kerberos cab be used for user authentication.when the user
wants to submit a job he/she can get delegation token followed by block
access token to access data from HDFS.So the client is overloaded with
initial 2 tickets (kerberos) TGT(Ticket grating Ticket),ST (service
ticket)followed by delegation token and block access token..Is that right??
suggestions plz...
regards
sujitha
