Zhijie Shen commented on MAPREDUCE-5157: ---------------------------------------- {quote} Oh and I suppose, with the latest patch, branch-1 sorter works against hadoop-2, right? {quote} Yes, given MAPREDUCE-5156 is fixed together. > Sort in hadoop-1 examples is not binary compatible with hadoop-2 mapred.lib > --------------------------------------------------------------------------- > > Key: MAPREDUCE-5157 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5157 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Reporter: Zhijie Shen > Assignee: Zhijie Shen > Attachments: MAPREDUCE-5157.1.patch, MAPREDUCE-5157.1.patch > > > In SORT example, org.apache.hadoop.mapred.lib.InputSampler.Sampler is used in > hadoop-1. However, after upgrading to hadoop-2, > org.apache.hadoop.mapred.lib.InputSampler is modified to extend > org.apache.hadoop.mapreduce.lib.partition.InputSampler, and the inner class, > Sampler, has been moved to the superclass. Therefore, hadoop-1 SORT can not > find Sampler when it runs with hadoop-2 framework. -- This message is automatically generated by JIRA.
