Konstantin Shvachko commented on HADOOP-4014:
---------------------------------------------
Yes, FileNotFoundException is thrown instead of the custom IOException, which
changes the description returned. E.g.
{code}
08/10/03 22:32:17 INFO cli.TestCLI: Expected output:
[copyFromLocal: /user/wrongdata: No such file or directory]
08/10/03 22:32:17 INFO cli.TestCLI: Actual output:
[copyFromLocal: File /user/wrongdata does not exist.
{code}
It is really a bad idea to verify correctness based on an exception description.
So now the question is whether these descriptions are a part of the CLI api and
it is going to be an incompatible change if I modify the "Expected output"?
