Unable to benchmark hadoop on k8s-cluster

[shashank855]

• I have deployed HDFS on k8s-cluster following the HDFS repo readme. I have used OpenEBS for the HDFS volumes. All components are running fine.
• Now I want to benchmark hdfs. I tried using TeraGen, I exec inside hdfs client pod, went to path /opt/hadoop-2.7.2/share/hadoop/hdfs and run this command: hadoop jar hadoop-hdfs-2.7.2-tests.jar TestDFSIO -write -nrFiles 1 -fileSize 1000 . But it didn't worked and the folowing output.

root@my-hdfs-client-544d894fc7-vnljw:/opt/hadoop-2.7.2/share/hadoop/hdfs# hadoop jar hadoop-hdfs-2.7.2.jar TestDFSIO -write -nrFiles 1 -fileSize 1000
Exception in thread "main" java.lang.ClassNotFoundException: TestDFSIO

	at org.apache.hadoop.util.RunJar.run(RunJar.java:214)
	at org.apache.hadoop.util.RunJar.main(RunJar.java:136)

I don't khow how to proceed. I didn't found any steps or reference docs on the official github repo.
