Subject About ant Hadoop
Date Wed, 19 Sep 2012 07:02:36 GMT

         I revise the source codes of hadoop-1.0.3 and use ant to recompile
hadoop. It compiles successfully. Then I "jar cvf hadoop-core-1.0.3.jar *"
and copy the new hadoop-core-1.0.3.jar to overwirite the $HADOOP_HOME/
hadoop-core-1.0.3.jar in every node machine. Then I use hadoop to test the
wordcount application. But the application halts at map 0% reduce 0%.

         Does anyone give suggestions?

Thanks a lot.
