> History server will be unavailable if there is an event log file with large size.
> Large size here means the replaying time is too long.
> *We can fix this to add a timeout for event log replaying.*
> *Here is an example:*
> Every application submitted after restart can not open history ui.
> !not-found.png!
> *From event log directory we can find an event log file size is bigger than 130GB.*
