Subject [jira] [Updated] (HDFS-6391) Get the Key/IV from the NameNode for encrypted files in DFSClient
Date Fri, 30 May 2014 17:19:03 GMT

     [ https://issues.apache.org/jira/browse/HDFS-6391?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Charles Lamb updated HDFS-6391:

    Attachment: HDFS-6391.1.patch

The attached diffs put some of the initial plumbing to connect Crypto{Input,Output}Streams
to the DFSClient as well as to pass the Key/IV pair around in the HDFS/NN protocol. Keys and
IVs are hardcoded. I have hardwired the crypto stream creation out with an if (false) so that
it doesn't break other users of the branch.

> When creating/opening and encrypted file, the DFSClient should get the encryption key
material and the IV for the file in the create/open RPC call.
> HDFS admin users would never get key material/IV on encrypted files create/open.
