Virajith Jalaparti commented on HADOOP-15106:
---------------------------------------------
Minor comment -- How about moving {{InvalidPathHandleException}} above
{{IOException}} in the javadoc to be consistent with others like
{{getFileStatus}} (e.g., {{FileNotFoundException}} goes above
{{IOException}}).? Other than that, lgtm.
> FileSystem::open(PathHandle) should throw a specific exception on validation
> failure

> Callers of {{FileSystem::open(PathHandle)}} cannot distinguish between I/O
> errors and an invalid handle. The signature should include a specific,
> checked exception for this case.
