------------------------------

             Summary: PerformanceEvaluation should provide user friendly hint when client
threads argument is missing
                 Key: HBASE-16122
                 URL: https://issues.apache.org/jira/browse/HBASE-16122
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


I tried to run this command:

hbase pe --rows=10000 --nomapred --valueSize=2000000 sequentialWrite
{code}
java.util.NoSuchElementException
	at java.util.LinkedList.removeFirst(LinkedList.java:270)
	at java.util.LinkedList.remove(LinkedList.java:685)
	at org.apache.hadoop.hbase.PerformanceEvaluation.parseOpts(PerformanceEvaluation.java:2077)
	at org.apache.hadoop.hbase.PerformanceEvaluation.run(PerformanceEvaluation.java:2122)
	at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:76)
	at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:90)
	at org.apache.hadoop.hbase.PerformanceEvaluation.main(PerformanceEvaluation.java:2159)
{code}
Number of client threads argument was missing.
PerformanceEvaluation should print user friendly message informing user of the missing argument.
