I had this issue too in Dev during our automated oozie sharelib creation process--which was essentially doing this: oozie-setup sharelib create -fs hdfs://devhost:8020 -locallib /usr/lib/oozie/oozie-sharelib-yarn.tar.gz The error I was seeing was: org.apache.hadoop.security.AccessControlException: Permission denied: user=oozie, access=WRITE, inode="/user":hdfs:supergroup:drwxr-xr-x It wasn't exactly clear to me at first as it seemed like a permissions error given the error above. For me it was solved by changing the address that the service was listening on in /etc/hadoop/conf/core-sitse.xml. Mine was previously listening on "localhost:8020." (127.0.0.1) So to be clear my fix was this: <configuration> <property> <name>fs.defaultFS</name> <value>hdfs://0.0.0.0:8020</value> </property> && then bounce the service with hadoop-hdfs-namenode restart optional: validate with netstat -tupln | grep '8020' Hope this helps someone else out. -cmcc
