Suresh Srinivas commented on HADOOP-9094:
-----------------------------------------
bq. 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.
Given that the new exceptions format the exception message in certain way,
making the following change:
# Move the message formatting to a static method
# Have PathNotFoundException subclass FileNotFoundException. It formats the
exception message using the utility.
# PathAccessException - rename it as PathAccessControlException. Make it a
subclass of AccessControlException. It also formats the exception message using
the utility.
Other alternative is to blow away the Path*Exception in above cases and use the
super class I have propose. The message in the exception can still use the
utility to format the message.
I am leaning towards the second option.

> HADOOP-9093 moved path related exceptions to o.a.h.fs. This jira tracks
> adding interface audience and stability to notation to those exceptions. It
> also tracks the comment from 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.
