This does change the behavior, so we need to be careful. I think it is easier 
to reason about the system when it uses a clean environment. If this makes 
sense, I will change our jobs to put the variables in 
bin/impala-config-local.sh (which works fine).

File bin/single_node_perf_run.py:

http://gerrit.cloudera.org:8080/#/c/24430/1/bin/single_node_perf_run.py@96
PS1, Line 96:   if type(cmd) is list:
            :     cmd = " ".join([pipes.quote(arg) for arg in cmd])
            :   cmd = "source {0}/bin/impala-config.sh && 
{1}".format(IMPALA_HOME, cmd)
            :   # Set env={} to use a clean environment. Existing environment 
variables can cause
            :   # complicated interactions. For example, this script runs

bin/impala-config-local.sh works fine.
