> 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();
>     }
