Subject [jira] [Created] (HBASE-10425) [0.89-fb] Isolate assignment plan on subset of machines

Adela Maznikar created HBASE-10425:

             Summary: [0.89-fb] Isolate assignment plan on subset of machines
                 Key: HBASE-10425
                 URL: https://issues.apache.org/jira/browse/HBASE-10425
             Project: HBase
          Issue Type: New Feature
          Components: Region Assignment
    Affects Versions: 0.89-fb
            Reporter: Adela Maznikar
            Assignee: Adela Maznikar

We use AssignmentPlan to decide on favored nodes for regions. Right now we include all machines
from the cluster in the assignment plan of a table. We want ability to limit the number of
machines when assigning regions. This will help us to isolate the failure domain in case different
users are using the cluster (in case someone is misusing the cluster, hopefully just a subset
of machines would be affected).
