Harsh J created MAPREDUCE-6194: ---------------------------------- Summary: Bubble up final exception in failures during creation of output collectors Key: MAPREDUCE-6194 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6194 Project: Hadoop Map/Reduce Issue Type: Improvement Components: task Affects Versions: 2.6.0 Reporter: Harsh J Priority: Minor
MAPREDUCE-5974 added in ability to instantiate multiple OCs, but if none of them are able to load it "throws" only a final a generic message: {{"Unable to initialize any output collector"}} The older behaviour was to throw the actual instantiation exception back, so it makes it to client logs with an actual meaningful error. Now the clients need to go take a look at the task's logs to find the WARNs that represent the failure in instantiation. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
