------------------------------------------------

So you will want the compaction chore to start by default after one day only?  
Any way things are configurable so should be ok in my opinion. 

> Add delay for the first execution of ExpiredMobFileCleanerChore and 
> MobFileCompactorChore

> Currently, the ExpiredMobFileCleanerChore and MobFileCompactorChore are 
> executed immediately when the master is started. At that time most of regions 
> are not online, running these chore is a waste. We need to add a delay for 
> them, now in the patch, we will use the interval as the initial delay.
