Steps to complete a graceful shutdown of Datameer:

  1. Pause the Job Scheduler located under the Administration tab in Datameer.
  2. Wait for current jobs to be marked as completed.
  3. When all jobs have been completed, use the "stop" command on conductor.sh
  4. After the Datameer application has been stopped, preform needed maintenance.
  5. With all maintenance completed, resume Datameer using the "start" command on conductor.sh.
  6. Under Datameer's Administration tab, resume the Job Scheduler. 

Note:

If a maintenance is needed sooner than the time it takes all jobs to complete, during step #2 the administrator can elect to force cancel current jobs.
