Jitendra Nath Pandey commented on HDFS-1813:
--------------------------------------------
The problem #2 is related to federation, but others exist in trunk also. I will
first fix it in federation branch. I will mark this jira for federation branch.
> Authentication using BlockToken in RPC to datanode fails.

> Key: HDFS-1813
> URL: https://issues.apache.org/jira/browse/HDFS-1813
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Jitendra Nath Pandey
> Assignee: Jitendra Nath Pandey

> 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.
