logs not available for some jobs

[#1]

when i check logs for application it shows logs not available. Aggregation may not be complete

[#2]

@Anurag Mishra

The application may not have complete logging details if the application is still running, that time the end message in the log would be "Aggregation may not be complete"

Also, refer to link for more details on log aggregation.

application is succeeded, but logs are not available. yarn.log-aggregation-enable is set to true
