stuck in "waiting for the test to start..." and then show parse error

[sj82516]

I am running on mac osx / jmeter 3.2 / python 2.7
I have test jmeter test file and it works fine.

When I start

count="1" /python/jmeter-ec2/jmeter-ec2.sh

The ec2 instance is created and run successfully.
But it would stuck in "waiting for the test to start..." and nothing show up.
When I stop the process, it would show

processing results...(standard_in) 2: parse error
/jmeter-ec2/jmeter-ec2.sh: line 926: [: : integer expression expected

close this issue. I faced the same issue with #91 and solved by the comment.
Thanks.
