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.
