RegionServer UsedHeap Size is not right

RegionServer UsedHeap Size is not right

New Contributor

i,everyone

I Find a I found a strange question. As I know in Hbase region server

regionServerHeapSize=MemberStoreSIze +BlockSize+other,

default maxMemerStoresize is regionServerHeapSize*0.4 maxBlocSize is regionServerSize*0.4

but I fine my hbase regionServer is diferent through hbase WebUI

my regionserver heapsize is 8g. I seee memberStoore is 690M but usedHeapSize is 7301M

I Think usedHeapSize =MemberStoreSize +BlockSize(8*0.4)

usedHeapSize should be 730M+3.2G(8*0.4) =3.9G is not 7301M

Why is there such a big gap?Who can answer my doubts
