[jira] [Resolved] (HBASE-5277) Put AssignmentManager on a diet

     [ https://issues.apache.org/jira/browse/HBASE-5277?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-5277.
--------------------------

    Resolution: Invalid

Resolving as no longer pertinent.  Jimmy did a bunch of heavy lifting in AM.  It can still go on a diet but what is discussed here doesn't make sense any more.

> 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).
