URL: https://github.com/apache/hadoop/pull/3996#issuecomment-1066573970


   > Can you also comment on performance implications of this change? Specifically `ViewFileSystem.getTargetFileSystemPaths` may now require parsing strings into URIs on each usage, where does this impose a performance penalty?
   
   The performance impact of this change where we are creating the URI object when its needed as well as creating a dummy URI object to check the validity of the path.
   I created 100000 URI objects in less than a second ( It took 700 msec to be precise).
