----------------------------------------

             Summary: Example usage is not correct in "Transparent Encryption in HDFS" document.
                 Key: HADOOP-12779
                 URL: https://issues.apache.org/jira/browse/HADOOP-12779
             Project: Hadoop Common
          Issue Type: Bug
          Components: documentation
    Affects Versions: 2.7.2, 3.0.0
            Reporter: Takashi Ohnishi


It says
{code}
# As the normal user, create a new encryption key
hadoop key create myKey
{code}
But, this actually fails with the below error.
{code}
$ hadoop key create myKey
java.lang.IllegalArgumentException: Uppercase key names are unsupported: myKey

{code}

Though I'm not sure why it is so, I think the document should be fixed to use only lowercase in key names.
