Zhijie Shen updated MAPREDUCE-5160: ----------------------------------- Issue Type: Sub-task (was: Bug) Parent: MAPREDUCE-5108 > Aggregatewordcount and aggregatewordhist in hadoop-1 examples can not find > their inner classes when running on Yarn > ------------------------------------------------------------------------------------------------------------------- > > Key: MAPREDUCE-5160 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5160 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Reporter: Zhijie Shen > Assignee: Zhijie Shen > > 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. -- This message is automatically generated by JIRA.
