--------------------------------
Summary: JobConrolCompile mis-logs after reducer estimation
Key: PIG-2884
URL: https://issues.apache.org/jira/browse/PIG-2884
Project: Pig
Issue Type: Bug
Reporter: Bill Graham
Assignee: Bill Graham
Attachments: PIG-2884.1.patch
This section of code produces erroneous logging messages:
{noformat}
mro.estimatedParallelism = estimateNumberOfReducers(nwJob, mro);
// reducer estimation could return -1 if it couldn't estimate
log.info("Could not estimate number of reducers and no requested or default " +
"parallelism set. Defaulting to 1 reducer.");
jobParallelism = mro.estimatedParallelism > 0 ? mro.estimatedParallelism : 1;
{noformat}
Fix is to use a if/then. Patch forthcoming.
