[GitHub] [rocketmq] lushilin opened a new issue #3603: Fetch or Commit ConsumeOffset may not use master broker firstly

lushilin opened a new issue #3603:
URL: https://github.com/apache/rocketmq/issues/3603


   **BUG REPORT**
   
   1. Please describe the issue you observed:
   ![image](https://user-images.githubusercontent.com/17663472/145169456-7ed12156-fa80-4a0d-a101-2aec6d41529d.png)
   如果一组brokerSet的组成是master节点(brokerId=0), slave节点(brokerId=16)，那么在hashMap遍历的时候，不一定会先遍历到master节点，因为hashMap的初始化capacity默认是16，0和16的hashcode % 16都为0，所以遍历的时候是不保序的。
   会导致在主节点存活的情况下，提交或者初始化拉取offset都从slave节点进行提交或者拉取。
