Rob Weltman commented on MAPREDUCE-4491: ---------------------------------------- If you want to use different encryption keys for different files (or even for different columns within the same file), how do you identify the right key from the Safe or Keystore, i.e. where is the mapping maintained? Would that be an additional layer on top of this? > Encryption and Key Protection > ----------------------------- > > Key: MAPREDUCE-4491 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4491 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Components: documentation, security, task-controller, tasktracker > Reporter: Benoy Antony > Assignee: Benoy Antony > Attachments: Hadoop_Encryption.pdf > > > When dealing with sensitive data, it is required to keep the data encrypted > wherever it is stored. Common use case is to pull encrypted data out of a > datasource and store in HDFS for analysis. The keys are stored in an external > keystore. > The feature adds a customizable framework to integrate different types of > keystores, support for Java KeyStore, read keys from keystores, and transport > keys from JobClient to Tasks. > The feature adds PGP encryption as a codec and additional utilities to > perform encryption related steps. > The design document is attached. It explains the requirement, design and use > cases. > Kindly review and comment. Collaboration is very much welcome. > I have a tested patch for this for 1.1 and will upload it soon as an initial > work for further refinement. -- This message is automatically generated by JIRA.
