Hi,
There is a JIRA issue about this problem, if I understand it correctly:
https://issues.apache.org/jira/browse/HADOOP-3743
Strange, that I searched all source code, but there exists only this control
in 2 places:
if (!(job.getBoolean("mapred.used.genericoptionsparser", false))) {
LOG.warn("Use GenericOptionsParser for parsing the arguments. " +
"Applications should implement Tool for the same.");
}
Just an if block for logging, no extra controls.
Am I missing something?
If your class implements Tool, than there shouldn't be a warning.
Cheers,
Rasit
