Ted Yu created HBASE-16122:
------------------------------
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.
