Yi Liang commented on HBASE-18229:
----------------------------------
most of above unit test are caused by Quota. In current SplitProcedure, we did
not consider Quota when split, some table may have max limit of n regions, so
we can not split this table when it already has n regions. Same to
mergerProcedure. new patch attached to fix it.
> create new Async Split API to embrace AM v2

> See HBASE-18105 for related information, this jira will change the logic of
> Path 1 in splitProcedure, the execution path will be:
> *HBaseAdmin.splitRegionAsync -> MasterKeepAliveConnection.splitRegion ->
> MasterRpcServices.splitRegion -> HMaster.splitRegion->
> AssignmentManager.submitProcedure*
> Master Will no longer as Rs and then Rs turn around to ask master to do the
> split operation.
