Subject [jira] [Created] (HDFS-1813) Authentication using BlockToken in RPC to datanode fails.
Date Thu, 07 Apr 2011 01:29:05 GMT
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.
