Yi Liu updated HDFS-5143: ------------------------- Status: Patch Available (was: Open) > Hadoop cryptographic file system > -------------------------------- > > Key: HDFS-5143 > URL: https://issues.apache.org/jira/browse/HDFS-5143 > Project: Hadoop HDFS > Issue Type: New Feature > Components: security > Affects Versions: 3.0.0 > Reporter: Yi Liu > Assignee: Owen O'Malley > Labels: rhino > Fix For: 3.0.0 > > Attachments: CryptographicFileSystem.patch, HADOOP cryptographic file > system.pdf > > > There is an increasing need for securing data when Hadoop customers use > various upper layer applications, such as Map-Reduce, Hive, Pig, HBase and so > on. > HADOOP CFS (HADOOP Cryptographic File System) is used to secure data, based > on HADOOP “FilterFileSystem” decorating DFS or other file systems, and > transparent to upper layer applications. It’s configurable, scalable and fast. > High level requirements: > 1. Transparent to and no modification required for upper layer > applications. > 2. “Seek”, “PositionedReadable” are supported for input stream of CFS if > the wrapped file system supports them. > 3. Very high performance for encryption and decryption, they will not > become bottleneck. > 4. Can decorate HDFS and all other file systems in Hadoop, and will not > modify existing structure of file system, such as namenode and datanode > structure if the wrapped file system is HDFS. > 5. Admin can configure encryption policies, such as which directory will > be encrypted. > 6. A robust key management framework. > 7. Support Pread and append operations if the wrapped file system supports > them. -- This message was sent by Atlassian JIRA (v6.1#6144)
