Specifically the oozie user. needs to be able to impersonate other users so he can kick off a job as the user who owns the oozie flow. HDFS allows you to configure these powerful users in the proxyuser settings. So to enable that you need to restart HDFS and yarn.</P><P>hadoop.proxyuser.oozie.groups</P><P>hadoop.proxyuser.oozie.hosts</P> Tue, 05 Jul 2016 21:23:18 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Oozie-restarts-Yarn-and-HDFS-in-the-process-of-reinstalling/m-p/113860#M33905 bleonhardi 2016-07-05T21:23:18Z Re: Oozie restarts Yarn and HDFS in the process of reinstalling it. https://community.cloudera.com/t5/Archives-of-Support-Questions/Oozie-restarts-Yarn-and-HDFS-in-the-process-of-reinstalling/m-p/113861#M33906 <P>Thank you @<A href="https://community.hortonworks.com/users/168/bleonhardi.html">Benjamin Leonhardi</A></P><P></P> Wed, 06 Jul 2016 11:54:52 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Oozie-restarts-Yarn-and-HDFS-in-the-process-of-reinstalling/m-p/113861#M33906 joshua_adeleke 2016-07-06T11:54:52Z
