Matteo Bertozzi updated HBASE-14614:
------------------------------------
Description:
New AssignmentManager implemented using proc-v2.
- AssignProcedure handle assignment operation
- UnassignProcedure handle unassign operation
- MoveRegionProcedure handle move/balance operation
Concurrent Assign operations are batched together and sent to the balancer
Concurrent Assign and Unassign operation ready to be sent to the RS are batched
together
This patch is an intermediate state where we add the new AM as
AssignmentManager2() to the master, to be reached by tests. but the new AM will
not be integrated with the rest of the system. Only new am unit-tests will
exercise the new assigment manager. The integration with the master code is
part of
was:Within a small interval, there could exists multiple region assignment
operations against 1 region server. To improve performance and reduce number
of RPCs between MASTER and RS, a dispatch will be implemented to group multiple
region assignment operation to 1 RPC (batch).
