Arvind Prabhakar commented on FLUME-1424:
-----------------------------------------

@Ralph - this is definitely one way to address this requirement. The advantage 
(and perhaps a disadvantage at the same time) of this approach is that it will 
only incorporate encryption for the put records. 

Another way to do this is to implement encryption at the LogFile.Writer/Reader 
level where the byte buffers are serialized between transaction boundaries. 
This approach will have a higher performance penalty but would encrypt every 
file channel record regardless of type.

                
> File Channel should support encryption
