yuhuiyang updated HBASE-23584:
------------------------------
Description: 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 .
(was: When store needs to open a storefile , it will create getFileStatus rpc

many files or open too many regions at once will cost very much time. So it is
possible to descrease the times for getFileStatus . )
