> We have HBase RegionServer and Hdfs DataNode running in one pod. When the pod
> restarts, we found that data locality is lost after we do a major compaction
> of hbase regions. After some debugging, we found that upon pod restarts, its
> ip changes. In DatanodeManager, maps like networktopology are updated with
> the new info. host2DatanodeMap is not updated accordingly. When hdfs client
> with the new ip tries to find a local DataNode, it fails.
