Hello,
I am trying to move to Hadoop MapReduce 0.21.0.
The corresponding tutorial still uses Tool and ToolRunner.
Yet both are deprecated. What would be the correct way to implement,
configure and submit a Job now? I was thinking in terms of:
Configuration configuration = new Configura
Hi Martin,
Neither Tool nor ToolRunner is deprecated in 0.21.0. I don't think

Hi Martin,
I think this is because the whole package is deprecated on the
MapReduce side (in package-info.java). I've opened
https://issues.apache.org/jira/browse/MAPREDUCE-2084 to address this.

Thanks,
