Vladimir Ozerov resolved IGNITE-3544.
-------------------------------------
Resolution: Won't Fix
> 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: Sub-task
> Components: IGFS
> Affects Versions: 1.6
> Reporter: Vladimir Ozerov
> Fix For: 2.1
>
>
> 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}}.
