0. Check out source code from SVN, you must build using ant, as described below. $ svn checkout https://svn.apache.org/repos/asf/incubator/hama/trunk ${HAMA_HOME} ${HAMA_HOME}/ant clean package 1. Modify ${HAMA_HOME}/conf/hama-env.sh. Make sure that $HADOOP_CONF_DIR and $HBASE_CONF_DIR are set to the location of your hadoop+hbase cluster' configurations file. And uncomment line "# export HAMA_CLASSPATH=$HADOOP_CONF_DIR:$HBASE_CONF_DIR" 2. cp ${HAMA_HOME}/build/hama-0.1.0-*.jar ${HAMA_HOME} Make sure that hama-x.x.x-{,examples}.jar are placed in ${HAMA_HOME} 3. ${HAMA_HOME}/bin/hama examples ex) ${HADOOP_HOME}/bin/hama examples rand 1000 1000 <dense|sparse> a ${HADOOP_HOME}/bin/hama examples rand 1000 1000 <dense|sparse> b ${HADOOP_HOME}/bin/hama examples mult a b 4 4. ${HAMA_HOME}/bin/hama shell Now, you are in the hama shell as below. hama > you can enjoy hama's power in hama shell! For examples: hama > a = Matrix.Random 10 10 // generate a random matrix(10,10) hama > b = Matrix.Random 10 10 // generate a random matrix(10,10) hama > c = Matrix.Random 10 20 // generate a random matrix(10,20) hama > d = ( a + b ) * c // do matrix computation |
