Yi Liang updated HBASE-18229:
-----------------------------
Release Note:
A new splitRegionAsync() API is added in client. The existing splitRegion()
and split() API will call the new API so client does not have to change its
code.
Move HBaseAdmin.splitXXX() logic to master, client splitXXX() API now go to
master directly instead of going to RegionServer first.
Status: Patch Available (was: Open)
> create new Async Split API to embrace AM v2
