loadgen ignore -m command line when using writing random data
-------------------------------------------------------------
Key: MAPREDUCE-3182
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3182
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2, test
Affects Versions: 0.23.0, 0.24.0
Reporter: Jonathan Eagles
Assignee: Jonathan Eagles
If no input directories are specified, loadgen goes into a special mode where
random data is generated and written. In that mode, setting the number of
mappers (-m command line option) is overridden by a calculation. Instead, it
should take into consideration the user specified number of mappers and fall
back to the calculation. In addition, update the documentation as well to match
the new behavior in the code.
