Mark Wagner created MAPREDUCE-5682:
--------------------------------------
Summary: Job Counters are not retrieved properly from web UI
Key: MAPREDUCE-5682
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5682
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv1
Affects Versions: 1.2.1
Reporter: Mark Wagner
Assignee: Mark Wagner
After MAPREDUCE-4962, most job counters are coming back as 0 because the web UI
retrieves them using the name instead of displayName, which is what is
expected:
{code}
/**
* Returns the value of the specified counter, or 0 if the counter does
* not exist.
*/
public synchronized long getCounter(String counterName) {
for(Counter counter: subcounters.values()) {
if (counter != null && counter.getDisplayName().equals(counterName)) {
return counter.getValue();
}
}
return 0L;
}{code}
