MR-279: SleepJob throws divide by zero exception when count = 0
---------------------------------------------------------------
Key: MAPREDUCE-2727
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2727
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.0
Reporter: Jeffrey Naisbitt
Assignee: Jeffrey Naisbitt
Fix For: 0.23.0
When the count is 0 for mappers or reducers, a divide-by-zero exception is
thrown. There are existing checks to error out when count < 0, which obviously
doesn't handle the 0 case. This is causing the MRReliabilityTest to fail.
