Adrian Woodhead updated HADOOP-2202:
------------------------------------
Fix Version/s: 0.16.0
Assignee: Doug Cutting
Affects Version/s: 0.15.0
Status: Patch Available (was: Open)
Fix should be self-explanatory when you look at the code.
As an aside, I always prefer to use the interface (e.g. List) rather than the
concrete implementation (e.g. ArrayList) wherever possible, especially in
methods which are in a public API (this is also recommended by Sun and many
others). I notice the Job class exposes the depending jobs as an ArrayList, I
think this should be changed to List. If you agree maybe a separate Jira issue
is in order? I'm quite happy to code up a patch for it.
