YARN owner permission
You must change the owner of the Yarn user. If you want to add a VPC or Compute cluster after migration, you must make changes for /user/yarn in HDFS.
- SSH to a cluster node
- You must have Sudo permission to perform this.
Change the owner of /user/yarn to
yarn:hadoopwith the command: sudo -u hdfs hdfs dfs -chown hdfs:supergroup /user/yarn
Change the permissions of /user/yarn to
drwxr-xr-xwith the command: sudo -u hdfs hdfs dfs -chmod 755 /user/yarn
