Subject [jira] [Commented] (HBASE-14614) Procedure v2: Core Assignment Manager
Date Sat, 08 Apr 2017 15:49:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15961867#comment-15961867

stack commented on HBASE-14614:
-------------------------------

v030 disables tests that try to move the hbase:meta off the master, disallowed by AMv2; i.e.
it should have been disallowed by AMv1 but it was loosey-goosey. Also disabled Mob failures
for now. Will come back to them.

>
> 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 HBASE-14616
