> When a store needs to open a storefile , it will create getFileStatus rpc
> twice or more . 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 .
