Subject [jira] [Updated] (HDFS-6724) Decrypt EDEK before creating CryptoInputStream/CryptoOutputStream
Date Thu, 24 Jul 2014 22:12:38 GMT

Andrew Wang updated HDFS-6724:

    Attachment: hdfs-6724.001.patch

Sorry about the delay here, had to do some KeyProvider API improvements along the way. Still
waiting on HADOOP-10981 to be committed to trunk (the EncryptedKeyVersion factory method),
but you can look at this combined patch for an idea.
