Installation went well but error happens when I try to upload a file with File View. </P><P> Before doing that, I created a local user as well as a home folder in HDFS for that user, using command below: </P><P style="margin-left: 20px;"> <EM>sudo -u hdfs hdfs dfs -mkdir /user/test </EM></P><P style="margin-left: 20px;"> <EM>sudo -u hdfs hdfs dfs -chown test:hadoop /user/test </EM></P><P> I could then create subfolder under /user/test. However, when uploading a file I got error </P><P style="margin-left: 20px;"> Unauthorized connection for super-user: root from IP 192.168.199.211 </P><P>Anything I may have missed? Thanks in advance!</P> Sat, 22 Oct 2016 10:00:45 GMT https://community.cloudera.com/t5/Support-Questions/File-View-Error-Unauthorized-connection-for-super-user-root/m-p/145021#M107593 tao_zhong 2016-10-22T10:00:45Z https://community.cloudera.com/t5/Support-Questions/File-View-Error-Unauthorized-connection-for-super-user-root/m-p/145022#M107594 <A rel="user" href="https://community.cloudera.com/users/13912/taozhong.html" nodeid="13912">@Tao Zhong</A>Try adding "hadoop.proxyuser.hdfs.hosts" and "hadoop.proxyuser.hdfs.hosts" properties in custom core-site.xml via ambari or in the file you aren't using ambari. Restart HDFS/MapR/Yarn services.

I fixed it by change "hadoop.proxyuser.hdfs.hosts" ambari server from "hdp1" to "*", where hdp1 is the host name of my ambari server. Any idea why at the first place only ambari server is put in here?</P> Sat, 22 Oct 2016 10:37:04 GMT https://community.cloudera.com/t5/Support-Questions/File-View-Error-Unauthorized-connection-for-super-user-root/m-p/145024#M107596 tao_zhong 2016-10-22T10:37:04Z https://community.cloudera.com/t5/Support-Questions/File-View-Error-Unauthorized-connection-for-super-user-root/m-p/145025#M107597 <P>Thats the default entry when configuring via Ambari.
