    Description

      Linux NFS client will issue `open(.. O_TRUNC); write()` when overwriting a file that's in nfs client cache (to not evict the inode, probably). Which will spectacularly fail on hdfs-nfs with I/O error.
      Example:
      $ cp /some/file /to/hdfs/mount/
      $ cp /some/file /to/hdfs/mount/
      I/O error

      The first write will pass if the file is not in cache, the second one will always fail.
