Chandra Sekhar K updated HBASE-28997:
-------------------------------------
Description:
Table Regions Total Locality value on the UI shows 1.0 even though some of the
regions locality value is zero. This is due to the rounding of happening inside
the String.format() function.
I have a table with 200 regions and 1 of the regions locality is zero, the
overall locality calculated value is ~0.99524385, but the String.format
function rounded of this value to 1.0.
If some of the table regions localtiy is zero then we should not show the total
Locality of the table as 1.0 as this can be misleading to the user.
