Running Terasort with DMExpress 7.13.7

The planned release of DMExpress 7.13.7 writes temporary sorting data to a directory chosen from a comma-separated list of directories specified by the dmx.sortwork.dirs property.

To run Terasort with the 7.13.7 release of DMExpress, use the following command:

# hadoop jar /opt/mapr/hadoop/hadoop-0.20.2/hadoop-0.20.2-dev-examples.jar terasort -Dmapreduce.job.map.output.collector.class=com.syncsort.dmexpress.hadoop.DMXMapOutputCollector -Dmapreduce.job.reduce.shuffle.consumer.plugin.class=com.syncsort.dmexpress.hadoop.DMXShuffleConsumerPlugin -Ddmx.home.dir=/usr/dmexpress -Ddmx.key.length=10 -D dmx.reduce.memory=3072 -D dmx.map.memory=1536 -libjars dmxhadoop_mrv1_mapr.jar -Ddmx.sortwork.dirs=/mapr/dmx/scratchSpace -Ddmx.mapr.nfs.mount=/mapr/perf /tsort_in/in /tsort_out/out
