https://community.cloudera.com/t5/Support-Questions/Permission-denied-when-trying-to-open-webhdfs-v1-op/m-p/31235#M53891 You are unfortunately impacted by a limitation described at: <A href="https://issues.apache.org/jira/browse/HDFS-5796" target="_blank">https://issues.apache.org/jira/browse/HDFS-5796</A><BR /><BR />You will need to use a custom filter class to avoid this (i.e. to auth browsers separately from regular WebHDFS auth access, probably by checking UserAgent strings/etc.), by implementing a sub-class of <A href="https://github.com/cloudera/hadoop-common/blob/cdh5.4.4-release/hadoop-common-project/hadoop-auth/src/main/java/org/apache/hadoop/security/authentication/server/AltKerberosAuthenticationHandler.java" target="_blank">https://github.com/cloudera/hadoop-common/blob/cdh5.4.4-release/hadoop-common-project/hadoop-auth/src/main/java/org/apache/hadoop/security/authentication/server/AltKerberosAuthenticationHandler.java</A><BR /><BR />Note that you can instead also opt to use the Hue File Browser, which is also more feature-rich in comparison.
