accessing HDFS Snapshot using HDFS NFS Gateway

Wed, 08 May 2019 12:47:39 -0700 

Hi!

I have mounted the HDFS root path over the HDFS NFS Gateway and I'm able to
do all kind of file operations. Now I want to read a from a HDFS snapshot
using the NFS mount,


snapshot in hdfs works and I can see it using hdfs dfs -ls


  hdfs dfs -ls /data/standard/.snapshot/s20190507-063223.621


  Found 2 items





  So when I try a ls command on the nfs mount I get an error.




  ll /mnt/hdfs/data/standard/.snapshot/s20190507-063223.621


  ls: cannot access /mnt/hdfs/data/standard/.snapshot/s20190507-063223.621:
  Input/output error​





  I'm using HDP 3.1.0





  Any ideas ?





  Best Regards
