9 years ago Based on the source code, it seems that a task can be restarted if it is in one of the following states:
- SUBMITTED
- PENDING
- PAUSED
- RUNNING
- WAITING_ON_ERROR
- WAITING_ON_FAILURE
I tried the RUNNING state with a Python task sleeping for 60 seconds and with maxNumberOfExecution set to at least 2:
import time
time.sleep(60)In that case a restart with ./bin/proactive-client -rt JOB_ID "Python_Task" seems to work.
If the maxNumberOfExecution is set to a lower value, then proactive-client reports that the restart has succeeded but the task fails.
The same test for restarting a task in a PAUSED state seems not to work.
Also, the proactive-client help command speaks about a delay parameter that cannot be set using the utility.
To summarize, the usage is not well documented and some cases seem not to work.
When restarting a paused task, we obtain this error on the interactive client
