Daryn Sharp commented on HADOOP-9093:
-------------------------------------
bq. I propose using FileNotFoundException instead of PathNotFoundException as
it is already extensively used. Similarly use AccessControlException instead of
PathAccessException. If folks agree, I will make that change in the next patch.
Alternatively we could at least make these exceptions subclasses of the
exception that I am proposing replacing them with.
I had considered that when I created these exceptions, but wanted all path
exceptions to derive from a common class. I suppose {{PathException}} could be
an interface and we copy-n-paste the base code - which is the main factor I
chose to derive from a base class.
> Move all the Exception in PathExceptions to o.a.h.fs package

> The exceptions in PathExceptions are useful for non shell related
> functionality as well. Making this available as exceptions under fs will help
> move some of the HDFS implementation code throw more specific exception than
> throwing IOException (for example see HDFS-4209).
