In one of my Dev Publisher instance cq-quickstart-6.3.0-standalone-quickstart.jar file got corrupted and its showing the size as '0' bytes. So now we have copied the cq-quickstart-6.3.0-standalone-quickstart.jar file from QA Author instance to Dev Publisher instance then we are able to successfully get the status of the AEM services running etc. Dev publisher URL is not working we are getting 404 error/site when cross checked in error.log for logs we found below error :
org.apache.sling.commons.scheduler.impl.QuartzScheduler No discovery available, therefore not executing job 'org.apache.jackrabbit.oak.plugins.index.AsyncIndexUpdate@5ec32f22' with name 'Registered Service.687' and config SINGLE.
Please help me out how to fix this issue and bring my Dev publisher instance back to running.
