How to execute Hadoop Job written in Java on Hadoop Environment -


I have class files loaded on the Hadoop file system. And I have also loaded the input file in HDFF. When I run the class file through the headop command in the terminal then I did not get the class error. Ex: I have HDFS content as WordCount. ClassWordCountMapper Classroom Conductor Reduce Class sample insp. TSS

Can someone correct me where I am doing wrong? Or can it be done in real?

Below we use the command line to run a Java MapraRes job on our 4-node Hadoop-2.2.0 cluster. it works fine. We run it by nomination, but any machine in the cluster should work fine. 

  help jar ~ / .. path ../mr_orchestrate / target / mr-orchestrate-1.0.jar com.rr .ap.orchestrator.mROrchestrate /user/hduser/in/Sample_15Feb2014.txt / User / hduser / out / out15Feb2014

You may need the "-libjars" option to add other library paths.

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
