创建Oozie工作流



One thing missed in the discussion above:

In core-site.xml you need to use the user with which oozie is started, as in the user that invoked the command "bin/oozied.sh start". For example: if you have "hadoop.proxyuser.bob.hosts" along with hadoop.proxyuser.bob.groups, then the user 'bob' would be required to start oozie using "bin/oozied.sh start".
