Hello!
I have tried to install JIRA 7.1.7 a couple of times and I am getting this strange error message during the 'Set Up Application Properties' stage of the initial JIRA configuration:
Error adding service: com.atlassian.scheduler.SchedulerServiceException: Unable to either create or replace clustered job: ImmutableClusteredJob[jobId=com.atlassian.jira.service.JiraService:10001,jobRunnerKey=com.atlassian.jira.service.DefaultServiceManager,schedule=Schedule[type=INTERVAL,intervalScheduleInfo=IntervalScheduleInfo[firstRunTime=null,intervalInMillis=43200000]],nextRunTime=Tue Jun 07 11:12:30 MSK 2016,version=1,rawParameters=[ACED000573720037636F6D2E676F6F676C652E636F6D6D6F6E2E636F6C6C6563742E496D6D757461626C6542694D61702453657269616C697A6564466F726D00...]].
I am running this on Ubuntu 14.04 LTS with a Oracle database.
