Chris Douglas commented on HADOOP-15106:
----------------------------------------
bq. Is there any unit test covering this?
Yes, the contract tests. I added more checks as part of HDFS-12882, but they're
not exhaustive. The negative cases are updated to catch
{{InvalidPathHandleException}} instead of {{IOException}} in the patch.
bq. How about moving InvalidPathHandleException above IOException in the
javadoc to be consistent with others like getFileStatus (e.g.,
FileNotFoundException goes above IOException)
Sure, np.
> 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,
