Subject [jira] [Updated] (HDFS-13208) RBF: Mount path not available after ADD-REMOVE-ADD
Date Wed, 28 Feb 2018 22:23:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-13208?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Wei Yan updated HDFS-13208:
---------------------------
    Description: 
To reproduce this issue, run the following commands at Router 1:
{code:java}
$ hdfs dfsrouteradmin -add /test1 ns1 /ns1/test1
$ hdfs dfsrouteradmin -rm /test1
$ hdfs dfsrouteradmin -add /test1 ns1 /ns1/test1{code}
"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.
