Devaraj Das updated HBASE-8344:
-------------------------------
Attachment: hbase-8344-1.txt
Patch that does the following:
1. Enhances the FavoredNodesLoadBalancer's methods (roundRobinAssignment and
randomAssignment) to work with previously chosen favored nodes for a given
region. This addresses both the case of AssignmentManager assign failures, and
RegionServer failures, to assign the regions to secondary/tertiary servers.
2. Avoids the creation of RackManager for every call to the constructor of
FavoredNodeAssignmentHelper.
3. Adds unit tests for (1).
> Improve the assignment when node failures happen to choose the secondary RS
> as the new primary RS
