> Affects Versions: 3.1.0
> Reporter: yanghuafeng
> Assignee: yanghuafeng

> When we are adding the mounttable entry, the router sever is terminated.
> Some error messages show in log, as follow:
> 2018-08-20 14:18:32,404 ERROR
> org.apache.hadoop.hdfs.server.federation.store.driver.impl.StateStoreZooKeeperImpl:
> Cannot get data for 0SLASH0testzk: null.
> The reason is that router server have created the znode but not to set data
> before being terminated. But the method zkManager.getStringData(path, stat)
> will throw NPE if the path has null value in the StateStoreZooKeeperImpl,
> leading to fail in adding the same mounttable entry and deleting the existing
> znode.
