Yi Liu updated HADOOP-10152:
----------------------------

    Description: To be easily seek and positioned read distributed file, the 
length of encrypted file should be the same as the length of plain file, and 
the positions have 1:1 mapping.  So in this JIRA we defines distributed file 
cipher InputStream(FSDecryptorStream) and OutputStream(FSEncryptorStream). The 
distributed file cipher InputStream is seekable and positonedReadable.  This 
JIRA is different from HADOOP-10151, the file may be read and written many 
times and on multiple nodes.

> Distributed file cipher InputStream and OutputStream which provide 1:1 
> mapping of plain text data and cipher data.
