      Description

      To reproduce this issue, run the following commands at Router 1:

      $ hdfs dfsrouteradmin -add /test1 ns1 /ns1/test1
      $ hdfs dfsrouteradmin -rm /test1
      $ hdfs dfsrouteradmin -add /test1 ns1 /ns1/test1

      "hdfs dfs -ls hdfs://Router1:8020/test1" works well after step 1. After step 3 when we add /test1 back, Router 1 still returns "No such file or directory". 

      But after step 3, when we run cmd "hdfs dfs -ls hdfs://Router2:8020/test1" talking to another Router, it works well.

      From Router logs, I can see StateStoreZookeeperImpl and MountTableResolver are updated correctly and in time. Not find the root case yet, still looking into it.
