Steve Loughran commented on HADOOP-3733:
----------------------------------------
Given that distcp clearly never worked if there was a "/" in the secret key,
it's always been an intermittently available feature. But it is causing
problems, which HADOOP-14439 looks at.
I don't want to revert this, as it does a lot. But I think we should have
Path.toString() return the secrets,.,.after telling the user not to do it
whenever the FS instance is created. We could even add a wiki link to tell
users why it is wrong and what to do about it.
