jojochuang commented on issue #509: HBASE-22877 WebHDFS based export snapshot 
will fail if hfile is in archive directory

   Interesting to know this webhdfs behavior.
   I wonder if the behavior had changed recently, because on Hadoop 3, it does 
throw FileNotFoundException upon opening an non-existent file:
   
   ```
   
   curl http://nn1:20101/webhdfs/v1/abc?op=OPEN
   
{"RemoteException":{"exception":"FileNotFoundException","javaClassName":"java.io.FileNotFoundException","message":"File
 /abc not found."}}
   ```
