---------------------------------------
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}}.
