PI Estimator Testing:
time hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 10 100

TeraGen/TeraSort/TeraValidate Testing:
1. time hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar teragen 10485760000 /user/hduser/input  # 10,485,760,000=1000GB=1TB

2. time hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar terasort /user/hduser/input /user/hduser/output

3. time hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar teravalidate /user/hduser/output /user/hduser/validate

TestDFSIO Testing:
Usage:
hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-client-jobclient-2.5.0-cdh5.2.0-tests.jar TestDFSIO -read | -write | -clean [-nrFiles N] [-fileSize MB]

1. time hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-client-jobclient-2.5.0-cdh5.2.0-tests.jar TestDFSIO -write -nrFiles 10 -fileSize 1

2. time hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-client-jobclient-2.5.0-cdh5.2.0-tests.jar TestDFSIO -read -nrFiles 10 -fileSize 1

3. time hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-client-jobclient-2.5.0-cdh5.2.0-tests.jar TestDFSIO -clean
