HiBench benchmark using random-text-writer have issue in yarn, new hadoop 2.x

I had problems using Hibench 2.2 in new hadoop cluster, yarn.

when I used prepare.sh to make data used in wordcount and sort, DATASIZE and NUM_MAPS in configure.sh aren't recognized correctly.

So I edited some lines which looks like old code, after that, it was executed correctly.

it is original source code

#line: 39

# generate data
$HADOOP_EXECUTABLE jar $HADOOP_EXAMPLES_JAR randomtextwriter \
    -D test.randomtextwrite.bytes_per_map=$((${DATASIZE} / ${NUM_MAPS})) \
    -D test.randomtextwrite.maps_per_host=${NUM_MAPS} \
    $COMPRESS_OPT \
    $INPUT_HDFS

wordcount/bin/prepare.sh

and i changed it to

$HADOOP_HOME/bin/hadoop jar $HADOOP_HOME/hadoop-examples*.jar randomtextwriter \

    $COMPRESS_OPT \

    -D mapreduce.randomtextwriter.totalbytes=${DATASIZE} \

    -D mapreduce.randomtextwriter.bytespermap=$((${DATASIZE} / ${NUM_MAPS})) \

    $INPUT_HDFS

Naturally, test.randomtextwrite.maps_per_host can be changed to mapreduce.randomtextwriter.mapsperhost.

I hope that this post will help some people using hibench in yarn cluster.
