            Description

            Report from Subroto Sanyal:

            I am running CDH4u0 MR1; but while starting the task-tracker it logs:
            2012-09-25 05:37:55,818 WARN org.apache.hadoop.util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

            When I looked into the hadoop script it looks for the directory ${HADOOP_HOME}/lib/native
            For MR1 the ${HADOOP_HOME} is set to /usr/local/hadoop-2.0.0-mr1-cdh4.0.0 but, there is no native dependencies in /usr/local/hadoop-2.0.0-mr1-cdh4.0.0/lib/ but, the native dependencies are present at /usr/local/hadoop-2.0.0-cdh4.0.0/lib. If I copy the dependencies to the correct folder, then the problem is resolved.
