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. > ------------------------------------------------------------------------------------------------------------------ > > Key: HADOOP-10152 > URL: https://issues.apache.org/jira/browse/HADOOP-10152 > Project: Hadoop Common > Issue Type: Sub-task > Components: security > Affects Versions: 3.0.0 > Reporter: Yi Liu > Assignee: Yi Liu > Fix For: 3.0.0 > > > 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.
