Junhong Xu commented on HBASE-23584:
------------------------------------
Good job! What if we fetch all storefile FileStatus of a region once before any
stores and provide them to HStore when opening the region?
> Descrease rpc getFileStatus count when open a storefile

> 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 .
