    I am new to HDP 2.0.9 . I installed it through Ambari 1.4. And here is my summary of services :

    NameNode, HBase Master, Ganglia and Nagios servers installed on hdpm1.hdp.hadoop(master1)
    SecondaryNameNode, History and OOzie server , Resource manager and Hive Metastore installed on hdpm2.hdp.hadoop.

    I have 2 masters and 3 slaves. My input file is in HDFS for sure. I am not finding where my map reduce example jar files are. Can any1 please tell me where I can find them and on which node should I run the sample job.

    Thank you.

    Hi Again,

    I found the location and ran “hadoop –config /etc/hadoop/conf jar /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples-2.*.jar wordcount /tmp/input.txt /tmp/wcoutput1″. Now I want to run the “test” programs for benchmarking ! Where can I find them? Why do not I see them in the above locations ?.

    Actually I had a high difficulty in finding this example map reduce program examples. I found the location when I got some error in MapReduce 2 and saw the logs.
