Subject [jira] [Commented] (HADOOP-12779) Example usage is not correct in "Transparent Encryption in HDFS" document.
Date Tue, 09 Feb 2016 18:27:18 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15139350#comment-15139350
] 

Akira AJISAKA commented on HADOOP-12779:
----------------------------------------

+1, the fix looks good to me.
I found the usage of "hadoop key" is not documented anywhere, so we should document the usage
in a separate jira. In addition, we need to document that uppercase is not allowed for key
name.

in key names.
