Alejandro Abdelnur commented on MAPREDUCE-4932: ----------------------------------------------- +1. not very happy about the try/catch/rethrow-as-runtime for the interrupted-exception but I cannot think a better way of handling this as it is produced by the UGI.doAs() call in the getTaskCompletionEvents(int, int). > 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. -- This message is automatically generated by JIRA.
