@kellyzly I think copying the CryptoInputStream and CryptoOutputStream
classes would be more appropriate, but my question is do those class use
private interfaces? do they rely on underlying hadoop functionality that was
only added in hadoop 2.6 (like
org.apache.hadoop.fs.crypto.CryptoFSDataInputStream)? as mentioned if
functionality only in 2.6 we either can't use it or have to use reflection to
access.
You also seem to be using CryptoCodec which is private.
