Robert Stupp reopened CASSANDRA-11914:
--------------------------------------

The trades workload test (e.g. {{cassandra-stress user profile=https://raw.githubusercontent.com/mambocab/cstar_perf/belliottsmith-perf-jobs/regression_suites/trades.yaml ops\(insert=100,latest=100,range=1\) n=100M -rate threads=300 -pop seq=1..10K contents=SORTED read-lookback=uniform\(1..10K\) -insert visits=fixed\(10K\) revisit=uniform\(1..10K\)}}) fails with this patch with the following NPE:
{code}
...
  Generator Configs:
    millisecond: Clustering: Uniform:  min=50,max=200;
    second: Clustering: Uniform:  min=50,max=200;
  Query Definitions:
    latest: CQL:select * from trades where instrumentid = ? and day = ? ORDER BY second DESC, millisecond DESC LIMIT 1;Fields:samerow;
    range: CQL:select * from trades where instrumentid = ? and day = ? and second > ? ORDER BY second DESC, millisecond DESC LIMIT 100;Fields:samerow;
  Token Range Queries:
  Insert Settings:
java.lang.NullPointerException
	at org.apache.cassandra.stress.StressProfile.printSettings(StressProfile.java:116)
	at org.apache.cassandra.stress.settings.StressSettings.printSettings(StressSettings.java:383)
	at org.apache.cassandra.stress.Stress.run(Stress.java:95)
	at org.apache.cassandra.stress.Stress.main(Stress.java:62)
{code}

Can be reproduced locally by starting Cassandra from trunk locally and running the stress profile above.

> cassandra-stress has quite a lot of default settings and settings that are derived as side effects of explicit options. For people learning the tool and saving a clear record of what was run, I think it would be useful if there was an option to have the tool print all its settings at the start of a run.
