> Aggregatewordcount and Aggregatewordhist of hadoop-1 cannot run on hadoop-2 due to org.apache.hadoop.mapred.lib.aggregate.ValueAggregatorJob.createValueAggregatorJob(String
args[], Class<?> caller) is not available on hadoop-2 (see MAPREDUCE-5159).
> After I changed Aggregatewordcount and Aggregatewordhist to use createValueAggregatorJob(String
args[], Class<? extends ValueAggregatorDescriptor>[] descriptors), which is available
on hadoop-2, the two examples could be accepted and run on Yarn.
> However, the two examples still failed, because their inner classes, WordCountPlugInClass
and AggregateWordHistogramPlugin, cannot be found in runtime, respectively. Both the plugin
classes extend org.apache.hadoop.mapred.lib.aggregate.ValueAggregatorBaseDescriptor.
