I just created users in /home in edge node for users to work on hadoop. But users not able to run hive/Yarn jobs. My cluster is already kerberized. Is there any way to assign users to submit their jobs in edge node. Do we need to these users in hadoop/hdfs ? If cluster has kerberos and ranger is there any different way to do it ? Please suggest me. ... View more
