Subject [jira] [Commented] (HDFS-7243) HDFS concat operation should not be allowed in Encryption Zone
Date Thu, 16 Oct 2014 05:48:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14173405#comment-14173405
] 

Yi Liu commented on HDFS-7243:
------------------------------

Charles, the latest patch looks good and only one comment:
{code}
final INodesInPath trgIip = dir.getINodesInPath(target, true);
{code}
here, we should use {{getINodesInPath4Write}} instead of {{getINodesInPath}}.

> For HDFS encryption at rest, files in an encryption zone are using different data encryption
keys, so concat should be disallowed.
