This is looking good to me

http://gerrit.cloudera.org:8080/#/c/19796/3/bin/single_node_perf_run.py
File bin/single_node_perf_run.py:

http://gerrit.cloudera.org:8080/#/c/19796/3/bin/single_node_perf_run.py@332
PS3, Line 332:   parser.add_option("--split_profiles", action="store_true",
             :                     help="If true, query profiles will be 
generated as separate files")
I'm thinking that we might want the split profiles to be the default at some 
point. When we do, we could introduce a "--no_split_profiles" option that 
stores false into split_profiles. We can decide whether we should switch the 
default now or later.

This example over at the optparse documentation can help 
(https://docs.python.org/2.7/library/optparse.html#default-values )

Something like this might work:
parser.add_option("--split_profiles", dest="split_profiles", 
action="store_true", default=True, ...)
parser.add_option("--no_split_profiles, dest="split_profiles", 
action="store_false", ...)
