Owen O'Malley commented on HADOOP-6893:
---------------------------------------

I see now that there is a Util method that checks exist, but it still uses getFileStatus and catches the exception. There should be some way of asking an AbstractFileSystem whether a name exists that doesn't throw an exception.

> FileContext is missing a method to ask if a file or directory exists. Currently the only mechanism is to use getFileStatus, which throws an exception if the file doesn't exist, which I don't think is an appropriate use of that method.
