Description

RegionStates.java

  public Map<RegionState.State, List<HRegionInfo>> getRegionByStateOfTable(TableName tableName) {
    final State[] states = State.values();
    final Map<RegionState.State, List<HRegionInfo>> tableRegions =
        new HashMap<State, List<HRegionInfo>>(states.length);
    for (int i = 0; i < states.length; ++i) {
      tableRegions.put(states[i], new ArrayList<HRegionInfo>());
    }

    for (RegionStateNode node: regionsMap.values()) {
      tableRegions.get(node.getState()).add(node.getRegionInfo());
    }
    return tableRegions;
  }

It always returns all regions...
