I'm working with hadoop 0.20.2 using the new API contained in the package: org.apache.hadoop.mapreduce
I have noticed that MultipleInputs is under: org.apache.hadoop.mapred and when setting a path it asks for a JobConf: addInputPath(JobConf conf, Path path, Class<? extends InputFormat> inputFormatClass, Class<? extends Mapper> mapperClass) but JobConf is deprecated in 0.20.2 (so all my jobs are using Job instead of JobConf) I have noticed too that in 0.21.0 there's no such problem as MultipleInputs exist in org.apache.hadoop.mapreduce and when setting a path it asks for a Job: addInputPath(Job job, org.apache.hadoop.fs.Path path, Class<? extends InputFormat> inputFormatClass, Class<? extends Mapper> mapperClass) I was actually using 0.21.0 but had to downgrade to 0.20.2 as 0.21.0 can't report progress in the reduce context (and this feature is a must for me): https://issues.apache.org/jira/browse/MAPREDUCE-1905 So, wich would be the best way to use MultipleInputs? Should I change all my code to use the org.apache.hadoop.mapred insetad of the org.apache.hadoop.mapreduce classes? I am really confused here, thanks in advance -- View this message in context: http://lucene.472066.n3.nabble.com/MultipleInputs-and-org-apache-hadoop-mapred-package-in-0-20-2-tp1643587p1643587.html Sent from the Hadoop lucene-users mailing list archive at Nabble.com.
