Hi , We recently has added kerberos on our CDH4 cluster, and our java application hit error: Caused by: org.apache.hadoop.security.AccessControlException: Authorization (hadoop.security.authorization) is enabled but authentication (hadoop.security.authentication) is configured as simple. Please configure another method like kerberos or digest.
The above error is caused by below code: mFileSystem = FileSystem.get(uri,new Configuration(), loginUser); FileStatus[] statusArray = mFileSystem.listStatus(pathName) I am new to this area and can you shed some light on: how to configure the authentication method to Kerberos to avoid the above error ? Thanks and regards, Sophia
