Robert Kanter updated MAPREDUCE-4932:
-------------------------------------
Attachment: MAPREDUCE-4932.patch
That's a good point; not sure why I didn't see that it was 10 before.
New patch uses {{10}} instead of {{Integer.MAX_VALUE}}
> mapreduce.job#getTaskCompletionEvents incompatible with MR1

> Key: MAPREDUCE-4932
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4932
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 2.0.2-alpha
> Reporter: Robert Kanter
> Assignee: Robert Kanter
> Attachments: MAPREDUCE-4932.patch, MAPREDUCE-4932.patch,
> MAPREDUCE-4932.patch

> In MR1, {{org.apache.hadoop.mapreduce.Job#getTaskCompletionEvents}} takes one
> argument: {{int startFrom}}. In MR2, it now takes an additional argument:
> {{int numEvents}} (which is the max number of events to get). This makes
> them incompatible.
> I propose we add a second {{getTaskCompletionEvents}} method that simply
> calls the other one with {{numEvents}} set to {{Integer.MAX_VALUE}} to
> replicate the behavior of the MR1 version.
