dhruba borthakur commented on HDFS-1593:
----------------------------------------

Arun: The HighTide node is running with the same priviledges as the two 
NameNode(s). The NameNode can copy data from one datanode to another within the 
same cluster. The HighTide node can copy data from one datanode in one cluster 
to another datanode in another cluster. Can you pl explain if you see a 
security issue in here?

> Allow a datanode to copy a block to a datanode on a foreign HDFS cluster.
