Hi there, I download sandbox HDP_2.3.2_virtualbox.ova for evaluating the TDE(transparent data encryption) feature. After simple setup, the HDFS CLI works as expected; but I also want to see TDE works with NFS. As yo can see below, Both TDE and NFS works fine on their own. However, I can't make them to work together. In my tests, I created one encrypted /zone_encr dir and one unencrypted /zone_plain dir; I mounted the HDFS on /mnt/nfs. Test 1: Unencrypted zone works fine. copy file to/from /mnt/nfs/zone_plain/ works as epxected; Test 2: Encrypted zone not working. [hdfs@sandbox ~]$ cp test.txt /mnt/nfs/zone_encr/testx.txt cp: cannot create regular file `/mnt/nfs/zone_encr/testx.txt': Permission denied [hdfs@sandbox ~]$ cat /mnt/nfs/zone_encr/test2.txt cat: /mnt/nfs/zone_encr/test2.txt: Stale file handle Test 3: Giving hdfs all the KMS managed permissions After giving "hdfs" all the permissions in the KMS policy (did it on the Ranger web site http://127.0.0.1:6080/index.html#!/service/6/policies/18/edit ), I got different error when copying files to the directory: [hdfs@sandbox ~]$ cp test.txt /mnt/nfs/zone_plain/fromNFS.txt cp: cannot create regular file `/mnt/nfs/zone_plain/fromNFS.txt': Input/output error On the other hand, read works: [hdfs@sandbox ~]$ cat /mnt/nfs/zone_encr/test3.txt Any suggestion?
