[ http://issues.apache.org/jira/browse/HADOOP-560?page=all ]
Owen O'Malley updated HADOOP-560:
---------------------------------
Attachment: kill-state.patch
This patch:
1. Introduces an enum for the Task state, called TaskStatus.State.
2. The enum values match the old integer constants by name and value.
3. The TaskStatus' serialization is kept the same.
4. A bug based on confusion between the Job State and Task State values is
fixed (go type-safe enums!)
5. A new killed state is added for Tasks.
6. The web/ui for jobs shows the count for tasks that have been killed.
7. The code for converting the Task Status State to string in the web/ui has
been removed.
> tasks should have a "killed" state
