Master starts in paused mode after failure

Current Situation

• With JS-1511 and JS-441 a pause command is available that can be used from the start script when starting a JobScheduler Master instance.
• The paused start mode is available by a command line option of the start script.

Desired Behavior

• A JobScheduler instance can be configured to start in paused mode if a previous run failed to terminate correctly, e.g. in case of a JobScheduler crash, server crash or database crash.
• This includes the JobScheduler to check its database for the information about a previously successfully completed run. Should this not apply then a previous failure situation is assumed and JobScheduler is started in paused mode.
• This start mode applies exclusively if activated by a command line option -pause-after-failure
