Subject please help me to find the source files in the hadoop project
Date Sat, 05 Mar 2011 12:45:21 GMT
 Dear:

        Excuse me to disturb you with your valuable time!
        I am a new user (fan) to hadoop, and only touch it for about three
days,but i have strong interest about it, maybe later i will just work
around it.



        Last night I downloaded the stable version of hadoop-0.20.2, and run
it in my windows OS fine, from the site
http://apache.etoak.com//hadoop/core/.
        But this morning I downloaded the version of hadoop-0.21.0, and run
failed in the windows OS.

        Then I opened the project in my IDE of Eclipse, and try to compile
the project, but I found many source JAVA files are lost.

        Ex.  in JAVA file  org.apache.hadoop.tools.rumen.LoggedTask, the
following four files are missing:

        import org.apache.hadoop.mapreduce.jobhistory.Events;
        import org.apache.hadoop.mapreduce.jobhistory.JhCounter;
        import org.apache.hadoop.mapreduce.jobhistory.JhCounterGroup;
        import org.apache.hadoop.mapreduce.jobhistory.JhCounters;

        I try to search the files in the project use the IDE search funtion,
but failed to find them, also failed to locate them manually.



        But I surprise to find the missed files in the jar
hadoop-mapred-0.21.0-sources.jar.

        I am confused, what's the difference between the JAVA files in
project with files in the the source jar!

        would you like to explain me the issue, and make me can success to
run the project in my IDE.


        Thanks a lot!



        Look forward to your feed back.


Best wishes !
