>
> When a store needs to open a storefile , it will create getFileStatus rpc
> twice . So open a region with too many files or open too many regions at once
> will cost very much time. if namenode wastes too much time in rpc process
> every time (in my case 5s sometime) due to namenode itself's problem . So i
> think we can descrease the times for getFileStatus , this will reduce stress
> to namenode and consume less time when store open a storefile .
