---------------------------------------

             Summary: IGFS: Review info() semantics - should it return null or throw exception if file doesn't exist?
                 Key: IGNITE-3544
                 URL: https://issues.apache.org/jira/browse/IGNITE-3544
             Project: Ignite
          Issue Type: Task
          Components: IGFS
    Affects Versions: 1.6
            Reporter: Vladimir Ozerov
             Fix For: 2.0


1) Throw exception: clean and simple semantics, but if Hadoop/Spark/etc. products return null in this case, we could end up with hot path where exception is thrown. This would render bad performance.
2) Return null: always good perf, but additional null-checks will be required.

Alternatively:
- Have a method with exception semantics on public API, but use method with null semantics for {{IgniteHadoopFileSystem}}.
