Hi Kay, Do you want to use the new hadoop API? If yes, did you check this link ? https://cwiki.apache.org/confluence/display/OOZIE/Map+Reduce+Cookbook
"CASE-2: RUNNING MAPREDUCE USING THE NEW HADOOP API" For your second questions, I don't know any good such link. But this could be helpful : http://stackoverflow.com/questions/10986633/hadoop-configuration-mapred-vs-mapreduce Regards, Mohammad ________________________________ From: KayVajj <vajjalak...@gmail.com> To: cdh-u...@cloudera.org; "common-u...@hadoop.apache.org" <user@hadoop.apache.org> Sent: Monday, September 23, 2013 2:39 PM Subject: mapred Configuration Vs mapReduce configuration in Ooozie I am implementing an oozie workflow MR job . I was not sure if I have to use the mapred properties vs the mapreduce properties. I have seen that if mapreduce properties were to be used, it has to be set explicitly like JobConf.setUseNewMapper(boolean flag) How do I do the same in Oozie? Also another question, if I were to use the new properties where do I find the property names like "mapreduce.job.inputformat.class" These seem to be hidden in some private API. Thanks your answers are appreciated.
