When you will have figure how the command is working, you will have to understand the output ;)
This is how I just tried it from my HBase directory: bin/hbase org.apache.hadoop.hbase.PerformanceEvaluation randomRead 10 And this is the output (last lines): 10066326 56314 10171183 56385 10276040 56579 10380897 56553 Does ask me what it means ;) I have, so far, no idea.
