>  Several issues are causing this problem
> 1. The last LocatedBlock returned by getBlockLocations doesn't have BlockToken.
> 2. The blockPoolTokenSecretManager is not initialized before created rpc server in datanode.
> 3. The getReplicaVisibleLength API in datanode expects WRITE permission in the block
token, but the block tokens are generated with read permission only in getBlockLocations at
namenode.
