[jira] [Created] (HBASE-5277) Put AssignmentManager on a diet
Put AssignmentManager on a diet
-------------------------------
Key: HBASE-5277
URL: https://issues.apache.org/jira/browse/HBASE-5277
Project: HBase
Issue Type: Task
Reporter: stack
AM has five or six inner classes, it takes zk callbacks, it has distinct Maps that are supposed to be edited together (regions and servers) and that then have some interaction w/ notion of regionsInTransition, etc. It could do w/ a tune-up so it comes back into the realm of the penetrable (currently I'd not be surprised if its workings were beyond the ken of all who here code).

stack updated HBASE-5277:
-------------------------
Attachment: 5277v1.txt
Move RegionState out into its own package private class. Make new datastructure ServersAndRegions that manages the servers to regions and regions to servers Maps.
Not done yet. Cuts AM by 1k lines or about 8%. More to do.
