Questions on killing a job

[xinli-cm]

Hi, I just started playing with PaddleCloud and ran into an issue on killing a job. I tried the fit-a-line example according to the instructions and tried to stop the job by using paddlecloud kill_job --job_id=job-xxxxxxxxxxxxxxxxxxxxx. I could see the feedback is either <kill_job...done> or <kill_job...failed, (1013)job-xxxxxxxxxxxxxxxxxxxx is already killed>. However, when I ran the query_job command again, the job_status is not killed. Here is the screenshot.

I also found out that for free usage, the maximum container count per account is 2. Let's say if I started two jobs and killed them. Can I start a third one??

Thanks
