Subject kerberos security enabled and hadoop/hdfs/mapred users
Date Thu, 03 May 2012 23:08:45 GMT
do i understand it correctly that with kerberos enabled the mappers and
reducers will be "run as" the actual user that started them? as opposed to
the user that runs the tasktracker, which is mapred or hadoop or something
like that?
