Not the job, this should be logged as "start to run the task".
Also, we need some log to say "the task will run for XX minutes"

Review comment:
These ENV vars are required, I think we should do some check to make sure they present.
Otherwise, the cmd should fail directly and give users some explicit error.
Another thing is, all ENV vars should be using capital letters, e.g JOB_ID

do not set a default value when the error is not nil, this can cover some issues up.

`rumtimeMin` ---> `taskExecutionSeconds`

this should return the client an error, not just a server-side log
you can refer to, e.g https://github.com/apache/incubator-yunikorn-core/blob/e9ab51a96afc6a9ce9a320db800f514cf5e7ab50/pkg/webservice/handlers.go#L56

Review comment:
if the condition is not met, we need to print some logs as well.
E.g how many members are running out there, and what is the minMember, can you add that log as well?

do not set a default value when the error is not nil, this can cover some issues up.

Where is a `podAmount` and a `gangMember`?
To simplify this, I think we can only have 1 parameter, `gangMember`.

Review comment:
> Can we change the text to the following:
Gang scheduling simulation
The following script runs a given number of jobs, and each one is a simulated job that requires gang scheduling support. Where the job only starts to execute its tasks when the cluster has the min member of instances running.
```shell script
./cmd/gangDeploy.sh <job number> <pod amount> <gang member> <task run time(sec)>
```
Note, if you prefer to manually launch such jobs, please refer to the `gang-coordinator.yaml`, `gang-job.yaml`. Where:
1. `gang-coordinator.yaml`: the coordinator service used to coordinate the execution of each job's tasks
2. `gang-job.yaml`: the simulated job that requires gang members to be started before executing its tasks
