---------------------------------------
Summary: Replace RegionState.getRegionInTransition() Map with a Set
Key: HBASE-15843
URL: https://issues.apache.org/jira/browse/HBASE-15843
Project: HBase
Issue Type: Improvement
Components: master, Region Assignment
Affects Versions: 1.2.1, 2.0.0, 1.3.0
Reporter: Matteo Bertozzi
Assignee: Matteo Bertozzi
Priority: Trivial
Fix For: 2.0.0
RegionState.getRegionInTransition() is always used as a Set.
replace the Map with a Set, avoid some allocation and extra code.
also ClusterStatus.RegionInTransition has duplicated information.
The spec field contains the regionName (not encoded).
but we have the same info as part of the region_state with the HRegionInfo
serialized.
unfortunately I don't think we can get rid of 'spec' that being a required
field.

message RegionInTransition {
required RegionSpecifier spec = 1;
required RegionState region_state = 2;
}
