Ted Yu commented on HBASE-3507:
-------------------------------
I thought of adding setRequests() but didn't go that route.
There're two reasons:
1. Request for region comes in one by one normally. The setter isn't used.
2. When region splits, the request count goes half/half to daughter regions. It
is intuitive to assign the count in ctor.
I will upload another version which removes unnecessary changes in unit tests.
BTW unit tests pass on my Mac.
