[jira] [Updated] (HDFS-6392) Wire crypto streams for encrypted files in DFSClient

     [ https://issues.apache.org/jira/browse/HDFS-6392?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Charles Lamb updated HDFS-6392:
-------------------------------

    Attachment: HDFS-6392.3.patch

Yi, you are right about getWrappedStream(). I forgot that your implementation in Crypto{In,Out}putStream delegated #hflush and #hsync down. I also removed the code in HdfsDataInputStream#getWrappedStream().

I believe the latest .3 patch addresses all of yours and Andrews concerns.

> When the DFS client gets a key material and IV for a file being opened/created, it should wrap the stream with a crypto stream initialized with the key material and IV.
