> CDC needs the seek() method of org.apache.cassandra.db.commitlog.EncryptedFileSegmentInputStream implemented (currently throws an exception.)
> CommitLogs are read using this stream and the seek() method needs to be implemented so that mutations which are appended to the currently active commitlog can be read out in realtime.
>  
> Current implementation is:
> 	
> public void seek(long position)
>     {
>         // implement this when we actually need it
>         throw new UnsupportedOperationException();
>     }
