   1. 副本状态检测：
   我们当前的集群tag配置是： group_a:1 group_b:1 group_c:1
   出问题的tablet分布情况是：group_a:1 group_b:2  这3个replica 是stable， group_c: 1 的replica 
是unstable。通过下面这个代码，allocMap 和 
currentAlloMap做比较，符合REPLICA_MISSING_FOR_TAG，所以进行对应副本修复。

   2. 进行副本修复：
   在chooseProperTag 函数中寻找合适的tag返回进行修复，会上报no proper tag is chose for 
tablet。因为此时的allocMap 和 
currentAlloMap做比较时，currentAlloMap未考虑repliac是否stable，所以找不到对应的tag。

   综上所述，是因为副本状态检测和副本修复中关于currentAlloMap 的赋值前后条件不一致。
