HDFS Benchmark - Terasort output number of records

QUESTION

HDFS Benchmark - Terasort output number of records

Asked 2018-Jan-03 at 11:59

the question is related to a terasort example. Is there any parameter to change the amount of output records using terasort? The input generated with teragen is 65'536'000 but we are requested to run terasort and output 10'000'000 records. This request is part of a practice with Cloudera distribution, not a real case but benchmark on implementation practice. Teragen:

time hadoop jar opt/cloudera/parcels/CDH-5.13.1-1.cdh5.13.1.p0.2/lib/hadoop-0.20-mapreduce/hadoop-examples.jar teragen -Dmapreduce.job.maps=12 -Ddfs.blocksize=33554432 -Dmapreduce.map.memory.mb=512 -Dyarn.app.mapreduce.am.containerlauncher.threadpool-initial-size=512 65536000 /user/haley/tgen

Result:

Is there any parameter to change the amount of output records using terasort?

As far as I understand the source code of TeraSort.java, it seems to implement a custom partitioner, partitioning and sorting the full input. So there is no parameter to change that behavior.
