Abin Shahab updated HDFS-5804: ------------------------------ Attachment: (was: HDFS-5804.patch) > HDFS NFS Gateway fails to mount and proxy when using Kerberos > ------------------------------------------------------------- > > Key: HDFS-5804 > URL: https://issues.apache.org/jira/browse/HDFS-5804 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: nfs > Affects Versions: 3.0.0, 2.2.0 > Reporter: Abin Shahab > Attachments: HDFS-5804.patch > > > When using HDFS nfs gateway with secure hadoop > (hadoop.security.authentication: kerberos), mounting hdfs fails. > Additionally, there is no mechanism to support proxy user(nfs needs to proxy > as the user invoking commands on the hdfs mount). > Steps to reproduce: > 1) start a hadoop cluster with kerberos enabled. > 2) sudo su -l nfsserver and start an nfs server. This 'nfsserver' account has > a an account in kerberos. > 3) Get the keytab for nfsserver, and issue the following mount command: mount > -t nfs -o vers=3,proto=tcp,nolock $server:/ $mount_point > 4) You'll see in the nfsserver logs that Kerberos is complaining about not > having a TGT for root. > This is the stacktrace: > java.io.IOException: Failed on local exception: java.io.IOException: >
